说明书全文 | This application claims the benefit of U.S. Provisional Application Ser. No. 61/035,137 titled: “Seat Belt Extension Device” filed on Mar. 10, 2008. The present invention relates to the field of seat belts, more specifically to a resilient seat belt extension device that extends the location of the connection of a female receptacle and a male buckle of a conventional seat belt system towards center of the user's body. Conventional seat belt systems generally place the seat belt buckle very close to the seat surface. This design creates accessibility problems as the seat belt buckle is often hard to locate. This is especially true for large individuals, individuals with dexterity problems, and law enforcement officers whom need to get in and out of the car in an expedited manner. These accessibility problems also are present for users of child safety seats and individuals sitting side by side of each other. The conventional seat belt systems also present another problem for law enforcement officers in that the soft and flexible seat belt often tangles up with their gun, making it difficult for the officers to disengage from the seat belt. Hence, it is common for law enforcement officers to not wear a seat belt. This tangling problem also exists for individuals carrying other objects (e.g., cell phone, Blackberry®, personal digital assistant (“PDA”), etc.). The present invention provides a resilient seat belt extension device that solves the above-described problems associated with conventional seat belt systems. The device includes a female receptacle, a male buckle, and a resilient connector fixedly attached to the female receptacle on one end and the male buckle on another end, wherein (i) the female receptacle is adapted to engage a seat belt system's male buckle; (ii) the male buckle adapted to engage the seat belt system's female receptacle; and (iii) the connector is formed by the following steps: (a) attaching ends of an elongated material together forming the connector with two layers of elongated material; (b) placing a non-liquid compound between the two layers of elongated material wherein the compound is adapted to provide resiliency to the connector; (c) attaching the two layers of elongated material together; (d) curing the compound at a predetermined temperature. It is preferred that the female receptacle and the male buckle are adapted to be attached to the connector by looping the elongated material through each of them before the ends of the elongated material are attached together. The connector provides the device with the following resilient characteristics: The device, when engaged to the seat belt system's female receptacle but not engaged with the seat belt system's male buckle, has sufficient stiffness that it would not fall onto the seat and/or floor; but instead, it would be in a relatively erect position. The device, when engaged both to the seat belt system's male buckle and female receptacle, has sufficient compliance that it would bend and form around a user's body. Once the device is disengaged from the seat belt system's male buckle but is still connected to the seat belt system's female receptacle, the device recovers its relatively erect position allowing it to be easily located when needed. The present invention also presents a method of making the above-described device comprising: (i) providing a female receptacle adapted to engage a seat belt system's male buckle; (ii) providing a male buckle adapted to engage the seat belt system's female receptacle; (iii) providing an elongated material; (iv) looping the elongated material through an opening of the female receptacle; (v) looping the elongated material through an opening of the male buckle; (vi) attaching ends of the elongated material together forming the connector having two layers of elongated material; (vii) fixedly attaching the female receptacle at one end of the connector and the male buckle at another end of the connector; (viii) placing a non-liquid compound between the layers of elongated material wherein the compound is adapted to provide resiliency to the connector; (ix) attaching the two layers of elongated material together; and (x) curing the compound at a predetermined temperature. The features and inventive aspects of the present invention will become more apparent upon reading the following detailed description, claims, and drawings, of which the following is a brief description: The following term is intended to have the following general meanings as it is used herein. 1. Non-liquid: a compound does is not in a liquid state. For example, the compound can be in the form of gel, putty, paste, or the like. 2. Resilient and/or Resiliency: a quality that allows a device of the present invention to have the following characteristics. When the device is engaged to a seat belt system's female receptacle but not engaged with the seat belt system's male buckle, the device has sufficient stiffness that it would not fall onto the seat and/or floor; but instead, it would be in a relatively erect position. When the device is engaged both to the seat belt system's male buckle and female receptacle, the device has sufficient compliance that it would bend and form around a user's body (or an object such as a child safety seat). Once the device is disengaged from the seat belt system's male buckle but it is still connected to the seat belt system's female receptacle, the device recovers its relatively erect position allowing it to be easily located when needed. Referring to Referring to It is preferred that prior to attaching both ends of the elongated material 12 together, the elongated material 12 is attached to the female receptacle 15 and the male bucket 17 by looping the elongated material 12 through each of them (15, 17). The looping of the elongated material 12 through the female receptacle 15 is shown in Referring to Referring to The total length and width of the device 10 can be any length and width suitable for the desired application. For example, the length can be from about 4″ to about 24″, from about 8.5″ to about 15″, and from about 9″ to about 12″. For example, the width can be from about 1.5″ to 3″, from about 1.75″ to about 2.75″, from 1.875″ to about 2.5″. It is generally preferred that the total length of the device be greater than about 8″. A sleeve (not shown) can optionally be placed onto the connector 16 for additional support and/or for decorative purposes. The sleeve can be made to be either removable or not removable from the device 10. The sleeve can be constructed out of any art-disclosed suitable material. For example, in one embodiment, the sleeve has a width ranging from about 2″ to about 2.5″ and is constructed out of irradiated polyolefin (e.g., Part No. M23053/5, heat shrink tubing manufactured by Raychem located in Menlo Park, Calif., USA). The length of the sleeve depends upon the length of the connector 16 as it preferably shorter than the length of the connector 16. The sleeve is placed over the connector 16. Thereafter, heat is then applied to the sleeve to shrink it down for a snug fit around the connector 16. Additional label and/or tag can optionally be attached onto the connector 16 for informational purposes via suitable art-disclosed means (e.g., stitching, adhesive, or the like). The present invention presents a method of making the above-described device comprising providing the female receptacle 15 adapted to engage a seat belt system's male buckle 23 and a male buckle 17 adapted to engage the seat belt system's female receptacle 21. The method also includes providing the elongated material 12 and looping the elongated material 12 through (i) an opening of the female receptacle 15 and (ii) an opening of the male bucket 17. The method further includes attaching ends of the elongated material 12 together to form the connector 16 having two layers (18, 20) of the elongated material 12. The method also includes fixedly attaching the female receptacle 15 to one end of the connector 16 and fixedly attaching the male buckle 17 to another end of the connector 16. It is preferred that stitching is used for such fixedly attachments. The method further includes placing a compound 22 between the two layers (18, 20) of the elongated material 12 wherein the compound 22 is adapted to provide resiliency to the connector 16. After the compound 22 is placed between the two layers (18, 20) of the elongated material 12, the method includes attaching these two layers (18, 20) together via suitable art-disclosed attachment means such as stitching. The method also includes curing the compound 22 at a predetermined temperature until it can provide resiliency for the connector 16.
