Patent Application

This invention relates to the automotive field and more particularly to a system for passenger safety after an accident.
Vehicular accidents often leave the electrical system disabled or the door/window mechanism damaged, thereby preventing escape from a vehicle through a window. This lack of escape is especially dangerous when the vehicle ends up in a body of water or afire. Automobile glass is difficult to break. Being such, many people have died having been trapped within a vehicle, unable to provide sufficient leverage and/or strength as to break one of the windows and escape.
Window breakers are well known in the art as evidenced, for example, by U.S. Pat. No. 8,740,030 to Purdy, et. Al. which describes a window-mounted window breaker that has a spring-loaded plunger. This device is intended to be mounted on a window, for example, a bus window.
Another example is U.S. Pat. Pub. No. 2013/0146381 to Oosterhuis et al., shows an electronic window breaker that is integrated into a vehicle. Such relies on the electrical system being operational after an accident. Additionally, such is too easy to activate and may be inadvertently activated by, for example, a child.
Another example is U.S. Pat. Pub. No. 2009/0265858 to White describes a hand-held window breaking device. Such devices are good for carrying by first responders, but after an accident has occurred, finding such device within a vehicle is often difficult. The glove compartment may be inaccessible, if left in a cup holder, this device may migrate to a distant location in the vehicle after impact, if in water, this device may be difficult to see and find, etc.
Finally, in another example, U.S. Pat. Pub. No 2013/0167601 to Colasse describes a spring-loaded window breaker integrated into a vehicle key. This disclosure exemplifies the need to have the window breaker in a convenient, easy-to-find location so it is accessible immediately after an accident. This publication is hereby incorporated by reference to show an exemplary, spring-loaded window breaking mechanism. As vehicles are transitioning to “keyless” ignitions, vehicle keys (key fobs) will find themselves in pockets or at the bottom of purses and, therefore, may be difficult to access or may be thrown around the passenger compartment during an accident. In addition, this device is only useful in circumstances where the driver is conscious and able to remove the key (and window breaker) from the ignition and break a window. Damage to the steering column may prevent removal. This device does not offer a window breaker to other occupants of the vehicle that may not be able to reach the ignition area. The added weight of the window breaker to the key makes the key heavy and bulky, making it undesirable to carry on a day-to-day basis. Further, there have been past issues related to vehicle ignition systems when too much weight was added to a key (e.g. by ornamental objects or other keys attached to a keyring). Therefore, adaption of the device described in this publication will likely be minimal making it less effective at saving lives.
What is needed is a system that will be readily available to at least one occupant of a vehicle to break a window in an emergency.
In many countries and for most vehicles, by law, it is required to have seat belts for every passenger. The present invention integrates a window breaking mechanism with a seatbelt buckle making the window breaking mechanism readily available should an accident occur. By integrating the window breaking mechanism with the seatbelt buckle, it will be easy to find during the panic of the accident, and it will be tethered to the seatbelt, so as to not lose it if it slips out of one's hand.
In one embodiment, a window breaking system is disclosed including a seatbelt buckle interfaced to a vehicle through a seatbelt and a seatbelt receiver interfaced to the vehicle. A window breaker is integrated to the seatbelt buckle such that, in the event escape from the vehicle is needed, the seatbelt buckle is released from the seatbelt receiver and the window breaker is used to break a window, through which the user (occupant) is now able to escape.
In another embodiment, a method of exiting a vehicle is disclosed including disengaging a seatbelt buckle from a seatbelt receiver. The seatbelt buckle has an integrated window breaker. A movable portion of the integrated window breaker is then pushed against a window until and therefore, a glass-breaking spike of the integrated window breaker is hurled at the window. Now that the window is broken, the user exits through an opening vacated by the window.
In another embodiment, an apparatus for window breaking includes a seatbelt buckle with a window breaker integrated to the seatbelt buckle.
The invention can be best understood by those having ordinary skill in the art by reference to the following detailed description when considered in conjunction with the accompanying drawings in which:
Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.
Referring to
The window breaking mechanism 24 is molded to, affixed, or otherwise integrated into the seatbelt buckle 12. The seatbelt buckle 12 has a slot for accepting a seatbelt 20 (see
Referring to
Referring to
By having a window breaking mechanism 24 integrated into the seatbelt buckle 12, the window breaking mechanism 24 is readily available and easily located after an accident or when otherwise needed. Although there is no requirement that all seatbelt buckles 12 within a vehicle have the window breaking mechanism 24 integrated therein, it is anticipated that many or every seatbelt buckle 12 within a vehicle have a window breaking mechanism 24 included, as the driver may not be capable of operating the window breaking mechanism 24 and, having multiple window breaking mechanisms 24, one with each seatbelt buckle 12, other occupants are able to individually break their associated windows 60 after an accident.
Equivalent elements can be substituted for the ones set forth above such that they perform in substantially the same manner in substantially the same way for achieving substantially the same result.
It is believed that the system and method as described and many of its attendant advantages will be understood by the foregoing description. It is also believed that it will be apparent that various changes may be made in the form, construction and arrangement of the components thereof without departing from the scope and spirit of the invention or without sacrificing all of its material advantages. The form herein before described being merely exemplary and explanatory embodiment thereof. It is the intention of the following claims to encompass and include such changes.
