Nissan North America, Inc. (Franklin, TN)
The following description describes a vehicle door: A bracket is designed to support a window when it is opened and closed and a locking device for the door which is situated close to the bracket; an absorption member is constructed and placed to absorb energy produced by the force of the door order to safeguard the mechanism that locks it. The absorption member is comprised of an external body that defines an internal channel that is configured to receive the bracket with an interference fitting such that the absorption member is secured to the bracket.
A variety of internal components can be found in vehicle doors like locking mechanisms and window guides. The car door cavity housing these components can burst and become dislocated or damaged when it’s struck by another vehicle.
To address this concern, the present disclosure describes various embodiments of energy absorbers installed within the vehicle door to absorb the energy (force) of the impact and/or resist collapse of the vehicle door, thereby reducing (ifnot completely prevent) the damage to, or displacement of the various internal components.
In one aspect of the disclosed invention, the vehicle door is described which includes a bracket that is designed to hold a window during opening and closing, an internal locking mechanism for the door that is located proximate (e.g., near or near or to)the bracket as well as an absorption component that is configured and positioned to absorb energy from an impact with the vehicle door to thereby protect the mechanism for locking doors. The body of the absorption member defines an internal channel that receives the bracket. This interference fit assures the bracket is secured to the absorption members (e.g., without any adhesives or mechanical fasteners).
In certain instances, the body of the absorption component may include a deformable material (e.g., an expanded polypropylene foam).
In some embodiments the absorption member can include a plurality of stabilizers (e.g. the ribs) which extend outwardly from the body to the internal channel. For instance, in some embodiments, the number of stabilizers can include a first stabilizer that extends inwardly from a first face of the body as well as an additional stabilizer that extends inwardly from a second surface of the body which typically faces the first surface.
In some embodiments the internal channel can include a first portion that extends along a first direction, and a second portion that extends along the second axis. In such embodiments the second axis can connect with the first axis it is subtendan in angle, which lies substantially within the range of 115.degree. to 155.degree..
In some embodiments, the absorption member may be further equipped with an element of location which extends outwardly from the body. In these embodiments the location element could be configured for engagement with the bracket (and/or any fasteners that are used to secure the bracket within the vehicle door). In some examples the location element can be extended from the body to provide an opening to receive the bracket and/or fastener.
In some instances, the location elements may be extended outwards from the body in order that they can be placed below the bracket following attaching the members for absorption to the bracket.
A different aspect of the disclosure describes an absorption member that could be placed close to a locking mechanism that is on a vehicle door. It has a window that is supported when it is closed and opens. The absorption member is comprised of the body of which is a deformable materialthat permits the absorption member to absorb energy from an impact with the vehicle door to thereby protect the locking mechanism. The bracket is attached to the body by an internalchannel. The first dimension of the channel is determined by the bracket. The bracket’s larger width means that the channel inside expands to fit the bracket. This allows the bracket to be secured to the bracket without any adhesives or mechanical fasteners.
In certain embodiments the absorption member can comprise a number of internal stabilizers designed to be in contact with the bracket. In certain embodiments, for example, the plurality internal stabilizers could be configured as ribs that extend inwardly to form an internal channel.
In certain embodiments, the absorption member may also include an element of location that extends outwards from the body and is configured for engagement with the bracket (and/or any other fasteners that are used to secure the bracket in the vehicle door). In certain embodiments the location element could extend beyond the body in such a way that it defines a receiving space that can be configured to fit the bracket (and/or the fastener(s)).
In a further aspect of the present disclosure, a method of building a vehicle door is described that comprises: positioning the window guide channel inside the vehicle door; fixedly joining an elongated bracket to the vehicle door so that the bracket supports the window guide channel; and securing an absorption member to the bracket via inserting the bracket in a channel defined by the absorption member so that the bracket is placed with an interference fit to secure the absorption member to the bracket.
In certain embodiments, the mounting of an absorption component to the bracket could include deforming several internal stabilizers by entanglement with the bracket.
The mounting of the absorption members to the bracket in certain instances may require setting the absorption unit up so that a first inner stabilizer is located adjacent to the bracket’s first side and a second stabilizer adjacent to a bracket’s second side.
In certain instances, the bracket can be used to mount the absorption component to the bracket might be accomplished by positioning the absorption member so that a place element extending outwardly from a body of the absorption component is in contact with the bracket (and/or any fastenersused to attach the bracket to the vehicle door).

What is a patent?
A patent is granted by the government to safeguard an invention patents give the inventor with exclusive rights to develop, utilize and sell the invention?society gains when a innovative technology is introduced to the market. Benefits can be realized in the direct sense, since it may allow people to accomplish previously unattainable things, or indirectly, through the economic opportunities (business expansion and job creation) which the invention provides.
Many drug firms and researchers from universities are seeking patent protection for their research and developments. Patents can be granted for the creation of a product, process or method of making new materials. Patent protection must be granted to an invention that is beneficial or novel and is not already known by others in the same field.
Patents honor inventors who have commercially profitable inventions. They provide a reason for inventors to invent. Small businesses and inventors can be certain that they will receive a good return on their investment in the development of technology. They could earn a living from their work.
Businesses that have the capacity to:
Protect the latest products and services;
Increase the value, appearance, and visibility of your product on the market
Differentiate yourself and your products from the competition.
Access to business and technical knowledge and information;
Beware of using third-party content or losing valuable data, creative outputs or any other outputs that are creative.
Patents can transform an inventor’s knowledge into a marketable asset, which creates new opportunities to create jobs and boost business growth through joint ventures or licensing.
Small businesses that have patent protection will be more attractive to investors involved in the commercialization and development of technology.
Patenting could lead to the development of innovations and new ideas. This information can encourage innovation and may qualify to be protected by patents.
Patents can serve as a deterrent to untrustworthy third parties who profit from the efforts of an invention.
Patent-protected technology revenues that are commercially profitable can be used to finance technological research and development (R&D), which will improve the chances of better technology in future.
It is possible to leverage intellectual property ownership to convince investors and lenders that your product is a viable commercial value. One patent that is powerful could lead to many financing opportunities. You can use patents and other IP assets as collateral or security financing. Investors may also look at the patents you own to increase their company valuation. Forbes and other publications have pointed out that every patent can boost the value of your company by as much as $500,000 to $1 million.
A solid business plan that is well-designed is crucial for new businesses. It should be built on IP and explain the way your product or service is distinctive. In addition, investors will be impressed if you can show that your IP rights are secured or are in the process of becoming secure and they can support your business plan.
It is vital to keep an invention secret prior to filing for patent protection. Making an invention public prior to its filing often destroy its novelty and render it unpatentable. Therefore, pre-filing disclosures (e.g., for test-marketing investors, test-marketing, or any other business partners) must only be done upon signing a confidentiality contract.
There are a variety of patents and knowing the different types is crucial to protect your invention. Patents on utility cover new processes and machine creations. Design patents cover ornamental designs. Patents for utility are the most effective since they protect the creator from copycats as well as other competitors. Most often, utility patents are issued for alterations or improvements to existing inventions. Utility patents also cover improvements and changes in existing inventions. A process patent could cover the acts or methods of performing a specific act. However, a chemical composition will include the combination of ingredients.
How long does a patent last? Utility patents are valid for 20 years from the earliest filing dates, but their expiration dates may be extended because of patent office delays such as.

How to Search for Patents
The first step in obtaining your patent is to perform a patent search. You can do a google patent search or do a USPTO search. Patent-pending refers to the product that has been covered by the patent application. You can search the public pair to find the patent application. When the patent office approves the patent application, you can perform a patent search to locate the issued patent and your product has been granted patent. Alongside the USPTO search engine, you can also utilize other search engines such as espacenet, which is described below. A patent lawyer or patent attorney can help you through the procedure. Patents in the United States are granted by the US trademark and patent office, also known as the United States patent office and trademark office. This office also reviews trademark applications.
Are you looking for similar patents? These are the steps:
1. Think of terms to describe your invention, based on its purpose, composition, and usage.
Write down a brief detailed explanation of your invention. Avoid using generic terms like “device,” “process,” and “system.” Instead, think about synonyms for the terms you initially chose. Also, make note of key technical terms and key words.
To help you recognize terms and keywords, you can use the following questions.
- What’s the goal of this invention? Is it a utilitarian device or an ornamental design?
- Invention is a method to make something or carry out a function? Is it a product or process?
- What is the nature and purpose of the invention? What is the physical structure of the invention?
- What is the purpose of this invention?
- What are the technical terms and terms used to describe the nature of an invention? To assist you in finding the right terms, refer to an online dictionary of technical terms.
2. These terms allow you to look up relevant Cooperative Patent Classifications at Classification Search Tool. To determine the most suitable classification to your invention, go through the resulting classification’s class Schemes (class schedules). If you don’t see any results using the Classification Text Search, you might want to think about substituting the words for describing your invention using synonyms.
3. Check the CPC Classification Definition for confirmation of the CPC classification you’ve found. If the classification you have selected includes a blue square with a “D” on its left, clicking on the hyperlink will take you to the CPC classification definition. CPC classification definitions will help identify the scope of the classification, so you are certain to choose the one that is relevant. In addition they can provide search tips and other suggestions which could be helpful for further research.
4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. By focusing your search on abstracts and drawings that are representative, you can narrow down your search for the most relevant patent publications.
5. This list of patent publications is the best to check for connections with your invention. Take note of the specification and claims. It is possible to find additional patents by referring to the patent examiner and the applicant.
6. You can retrieve published patent applications that match the CPC classification you chose in Step 3. It is possible to use the same strategy of searching as in Step 4. You can narrow your results to the most relevant patent applications by looking at the abstract as well as the drawings that appear on each page. Next, examine all published patent applications carefully with particular attention paid to the claims, and other drawings.
7. You can look up additional US patent publications by keyword searching in the AppFT and PatFT databases, and also classification searching of patents that are not issued by the United States per below. You can also make use of search engines on the internet to find non-patent patent disclosures in literature about inventions. For example:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
