Abstract
Abstract An inflatable bumper for a vehicle which includes an elongated frame having an upper and a lower projecting lip and an inflatable tube of substantially ''''H'''' cross-sectional configuration including forward and rearward air chambers. The opposing lips of the frame extend between the chambers to hold the tube in place. An alternate embodiment includes a plurality of accordion-like lateral folds across the upper and lower surface of the front chamber to facilitate its resilient compression under collision conditions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
150 words
A pneumatic bumper for a vehicle comprising an elongated frame transversely mountable at either end of said vehicle, said frame comprising an upper and a lower lip, one extending toward the other and mounted at the forward and open end of said frame; a pneumatic chamber comprising a rearward portion, said rearward portion mounted between said lips and the ear of said frame, and a forward portion, said forward portion including a plurality of transverse folds having their horizontal axes substantially parallel to that of said frame, said folds further each including a transversely extending air sac in communication with said forward chamber portion for receiving air displaced from said forward portion of said chamber responsive to impact of an object thereagainst, and a central recessed portion included in the front surface of said forward chamber portion, said recessed portion substantially co-extensive with the length of said forward chamber portion.
Claim 2
Dependent Claim
150 words
A pneumatic bumper for a vehicle comprising an elongated frame transversely mountable at either end of said vehicle, said frame comprising an upper and a lower lip, one extending toward the other and mounted at the forward and open end of said frame; a pneumatic chamber comprising a rearward portion, said rearward portion mounted between said lips and the ear of said frame, and a forward portion, said forward portion including a plurality of transverse folds having their horizontal axes substantially parallel to that of said frame, said folds further each including a transversely extending air sac in communication with said forward chamber portion for receiving air displaced from said forward portion of said chamber responsive to impact of an object thereagainst, and a central recessed portion included in the front surface of said forward chamber portion, said recessed portion substantially co-extensive with the length of said forward chamber portion.
Claim 3
Dependent Claim
101 words
A pneumatic bumper for a vehicle comprising a closed frame attachable to one end of the vehicle, said frame including an upper and lower transverse lip extending one towards the other; a pneumatic tube extending substantially coextensive in length with said frame, said tube including a forward and a rearward chamber separated one from the other and retained in said frame by said lips, said forward chamber including a plurality of accordion-type folds extending transversely across the top and bottom outer surfaces of said forward chamber, said forward chamber having an overall width substantially larger than the width of said frame.
Claim 4
Dependent Claim
101 words
A pneumatic bumper for a vehicle comprising a closed frame attachable to one end of the vehicle, said frame including an upper and lower transverse lip extending one towards the other; a pneumatic tube extending substantially coextensive in length with said frame, said tube including a forward and a rearward chamber separated one from the other and retained in said frame by said lips, said forward chamber including a plurality of accordion-type folds extending transversely across the top and bottom outer surfaces of said forward chamber, said forward chamber having an overall width substantially larger than the width of said frame.
Claim 5
Dependent Claim
54 words
The combination as set forth in claim 2 wherein each of said transverse folds includes a central sac of relatively small dimension that extends across said fold in the lengthwise direction of said frame to provide flow of pressurized air into said sac from said forward chamber responsive to impact against said forward chamber.
Claim 6
Dependent Claim
32 words
The combination as set forth in claim 3 wherein there is included across the front surface of said forward chamber a concave central portion substantially coextensive in length with said forward chamber.
