N/A.
The present invention relates to automobile seatbelts and more specifically to improve the adjuster for holding together the lap seatbelt and the shoulder belt at a location where the shoulder belt does not rub against the neck of a seatbelt wearer.
Most seatbelts used in vehicles, such as automobiles, trucks, etc., have a lap seatbelt which extends across the lap of a wearer and also a shoulder belt which extends up from the attachment side of the belt across the wearer's shoulder, thus providing protection to the wearer from being thrown forward in the event of a sudden stop. The lap seatbelt holds the wearer in the seat and the shoulder strap prevents the wearer from jack-knifing forward. Most types of seatbelts are adjustable for different sized passengers and drivers. A lap seatbelt passes from one side of a seat across the seat to a releasable catch or attachment buckle on the other side of the seat. The belt passes through the catch or attachment buckle and then becomes a shoulder belt crossing over the front of a wearer and being attached at shoulder height above the seat at the side where the seatbelt is initially attached.
The problem with such types of seatbelts is that the angle the shoulder belt from the catch or attachment buckle often extends across the neck of the wearer and this becomes irritating as it rubs against the skin. My patented seatbelt adjuster U.S. Pat. No. 5,201,099 issued on Apr. 13, 1993 provides relief to this problem by holding the shoulder belt to the lap belt thereby avoiding skin contact of the shoulder belt.
Use of my original seatbelt adjuster has identified a number of deficiencies in the original design which this application serves to correct in a novel and inventive manner. For example the main tongue of the seatbelt adjuster proved to be insufficiently resilient particularly in hot weather where the interior temperature of an automobile may exceed 120° F. The tongue, under these temperatures, will soften and spread open thereby releasing the clip rendering it useless. Furthermore it was found that the seatbelt was getting caught in the closure snap thereby preventing the adjuster from sliding. Another deficiency of the original invention was that the belt would slip out from under the tongue during use. In some circumstances, the wearer's clothing would snag on the fastening clip. The deficiencies of the original seatbelt adjuster often resulted in the adjuster disengaging from the seatbelt rendering it useless.
The present invention provides novel and inventive improvements over the original seatbelt adjuster and overcomes the problems cited above.
In one embodiment of the invention there is an improved seat belt adjuster for holding a shoulder belt to a lap seat belt comprising a frame member having a top surface and a bottom surface, a front end and a rear end, a first side and a second side, a length, a first width and a second width. The second width is less than the first width giving the frame a pinched appearance. The frame member encloses a rectangular opening having a length and a width. The frame member further comprises a shoulder belt clip member having a first end fixed at a bottom rear end the frame member and a free end extending towards a bottom front end of the frame member. The clip member terminates adjacent to the bottom front end. The clip member has a first side and a second side and it is angled towards the rectangular opening. The clip member includes a length and width which is less than said length and width of the rectangular opening. The clip member also includes a first and a second parallel stiffening ridges projecting from a top surface of the clip member. The first parallel ridge is disposed a first distance inside of the clip member first side and the second parallel ridge is disposed the same distance inside of the clip member second side. The two parallel stiffening ridges commence at the fixed first end and terminate at a terminal end a second distance inside the free end of the clip member.
In one embodiment of the invention there is a rectangular aperture in the frame member for receiving a rectangular clasping member and a circular recess in the frame member for receiving a circular fastening pin.
The invention also includes a closure member having a length and a width, top surface, a bottom surface, a first side and a second side. The closure member further comprises a fixed end fixed to the top surface rear end of the frame member by a hinge located at said fixed end. The closure member pivots or folds from an open position to a closed position over the frame member thereby enclosing the lap belt. A free end of the closure member has a rectangular clasping member projecting therefrom. There is also a flat recessed portion between the fixed end and the free end defining a top of the lap belt containment channel. The circular fastening pin is located proximate to the fixed end.
In yet another embodiment of the invention there is a first set pins projecting from a top surface of the flat recessed portion of the closure member. The first set of pins is located proximate to a rear end of the flat recessed portion and a distance inside of the width. This first set of pins abuts a side of the lap belt and restrains the side from engaging the rectangular clasping member.
The improved seat belt adjuster of claim may also comprise a first, second, third and fourth pin projection upwards from the top surface of the frame and located at a corresponding first, second, third and fourth corner of the rectangular opening.
