This embodiment relates to automotive safety tools, and more particularly to an automotive safety tool for cutting a seat belt of a vehicle following an accident or some other serious vehicular mishap.
The use of seatbelts by drivers and passengers in automobiles can avoid or cut down the seriousness of injuries incurred in automobile accidents. In many areas, the use of automobile seatbelts has become mandatory. However, sometimes the use of seatbelts may be a fear on the part of the wearer that the seat belt might act as a trap preventing escape from the vehicle after an accident, in case of fire or the like. Contributing to this fear is the fact that often the release mechanisms of seatbelts and restraint harnesses are complicated and inconvenient to reach and often occupants may get stuck and thus it impossible to be released, so in many cases cutting the belt is the only way out.
Cutting devices, mounted somewhere reachably in the interior of the vehicle, have been used so that the belt can be cut in an emergency. However, such cutting devices are often unreachable after an accident because, as a result of the accident, the occupant strapped into his seat cannot reach the cutting device or the cutting device has been displaced by the accident and is no longer in a reachable place. The use of such a cutting device under high-stress accident conditions however is somewhat problematic since such a cutting device has to be used carefully to avoid injuries to the occupant. The resulting stress and chaos of an accident may lead the occupant to not fully carry out the required care of using such cutting devices, and consequently the occupant may inadvertently injury themselves while attempting to extricate themselves or to operate cutting devices.
In some existing seat belt cutting devices, a housing to be mounted on a safety belt is provided having an operating element so as to be movable across the safety belt. The housing has an at least partially U-shaped portion having legs extending essentially parallel to the plane of the belt so as to form a belt-receiving gap wherein a cutting blade with a cutting edge is so mounted that the cutting edge of the blade extends through the gap at an angle to the plane of the belt and is exposed only within the gap of the operating element so that the safety belt is guided within the gap onto the cutting edge so as to be severed if, after an accident, the operating element is moved across the safety belt. However, the device is complicated in design, difficult to open and clip on a seat belt.
Some other existing seat belt cutting devices provide an accessory that can be actuated in emergency situations to sever the belt and allow the belt user to be freed from the belt. This accessory has a pair of parallel blades one of which may be pulled along the other to sever the belt scissor-fashion when a force exceeding a predetermined minimum force is exerted on the blade pull. The movable blade may be spring-loaded so that simple actuation of a pushbutton or withdrawal of an operating pin allows the springs to push the movable blade across the fixed blade and sever the belt. Such an accessory is mounted on the seat belt in the middle of the chest of the user to make it readily accessible to the user or a rescuer in an emergency situation. However, it will be difficult to actuate the pushbutton or withdraw the operating pin in case of an emergency.
Another existing seat belt cutting device provides an apparatus wherein a unitary housing includes a “V” shaped slot defining an upper and lower planar wall, with an acute angle there between. The lower planar wall includes a blade member arranged essentially coextensively therewith, with the slot arranged for receiving a seat belt for emergency severing thereof. A plurality of hook and loop fasteners mounted to a first side wall of the housing is selectively and removably securable to a like plurality of hook and loop fasteners mounted to an associated seat belt. However, such devices cannot be fastened to a seat belt.
Therefore, there is a need for a seat belt cutting device that is mounted on the seat belt. Such a needed seat belt cutting device would provide safety and easy access. Further, the seat belt cutting device would be brightly-colored and always be readily accessible on the webbing when needed. Finally, the holder would be lightweight, reliable, affordable, compact, and user-friendly. The present embodiment accomplishes these objectives.
The present embodiment is a seat belt cutting device installed as a clip-on in a vehicle seat belt, for cutting the seat belt following an accident or some other serious vehicular mishap. The seat belt cutting device comprises a clip portion having a first half portion and a second half portion. The first half portion and the second half portion are attached together at a first end by means of a hinge and at a second end by means of a clip. The first half portion of the clip portion includes a blade portion extending along the mid section of the first half portion. The blade portion includes a movable blade and a handle attached to the blade to pull the blade along the midsection of the clip portion. Additionally, the movable blade may be spring-loaded and would contain a clip lock and snaps on one end.
The clip portion has a cavity with slotted parallel openings on either side to direct the seat belt there through. The clip may be released to open and close the clip portion around the seat belt for a tight fit. The button portion is raised higher to keep the belt firm. The movable blade has a protected serrated cutting edge disposed at one edge of the seat belt and inclined thereto for slitting the seat belt from side to side.
The seat belt cutting device can be any color for quickly and easily being seen and used when needed. The seat belt cutting device provides safety, easy access, and has a user-friendly design. Instead of being unable to escape a seat following a wreck or some other emergency, the seat belt cutting device could slice the seat belt in half to quickly exit the interior. The seat belt cutting device would also be lightweight, reliable, affordable, compact, and user-friendly.
Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

Referring to
The seat belt cutting device 10 provides the motorist with a quick and easy means of escaping the interior of the vehicle if the seat belt 14 is jammed or was malfunctioning. In the event the vehicle is involved in an accident or caught in fire and the seat belt 14 is jammed, the seat belt cutting device 10 is used to free the vehicle occupant. The vehicle occupant grips the seat belt cutting device 10 and moves the movable blade 26 by means of the handle 28 which in turn cuts through the seat belt 14 strap webbing in the cavity 30 of the clip portion 12. The vehicle occupant could be quickly freed from the seat for escape or extrication by the paramedics on the scene.
The seat belt cutting device 10 provides safety, easy access, and has a user-friendly design. Instead of being unable to escape a seat following a wreck or some other emergency, the seat belt cutting device 10 could slice the seat belt 14 in half to quickly exit the interior. This could mean the difference between life and death in a fire, flood, or following a collision when immediate medical assistance is required. The seat belt cutting device 10 would also be lightweight, reliable, affordable, compact, and user-friendly.
While a particular form of the invention has been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
