Abstract
Abstract A safety roof liner is disclosed which reduces the possibility of injury to a race car driver during a rollover accident. The safety roof liner comprises a generally rectangular sheet of high strength fabric material with front and rear edges, and opposite side edges. Each of a pair of straps manufactured from a high strength fabric material is attached along one of the opposite side edges and has a front end portion extending beyond the front edge of the sheet and a rear end portion extending beyond the rear edge. A releasable fastener, such as a slide adjuster, is used to fasten the end portions of the straps to the front and rear transverse braces of a roll cage in the race car. The rectangular sheet also has grommets transversely spaced apart along the front and rear edges of the sheet. The grommets are adapted to receive a separate fastening device such as a plastic tie wrap to further secure the safety roof liner to the roll cage. During a rollover accident where the roof is torn off, the safety roof liner as disclosed reduces the possibility of injury to the driver's extremities which may otherwise extend through the open roof of the race car.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
254 words
A motor vehicle having provision to retain a passenger's extremities within the automobile in the event of a rollover comprising: a motor vehicle frame which defines a passenger compartment which includes a pair of spaced apart transverse brace members located generally above the passenger compartment; a generally rectangular sheet of a predetermined high strength substantially non-stretching fabric material, with the sheet defining front and rear edges which are disposed generally parallel to and adjacent said pair of spaced apart brace members, and opposite longitudinal side edges; a pair of high strength substantially non-stretching and continuous fabric straps of high strength fabric material attached along respective ones of the longitudinal side edges of the sheet, with each of said straps having a forward end portion which extends longitudinally beyond the front edge of the sheet, and a rear end portion which extends longitudinally beyond the rear edge of the sheet, said forward end portion of each of said fabric straps looping about one of said transverse brace members, and said rear end portion of each of said fabric straps looping about the other of said transverse brace members; fastening means attached to each of said forward and rear end portions of each of said substantially non-stretching straps and securing each of said forward and rear end portions to itself to thereby maintain the forward and rear end portions looped about the associated brace members; such that the rectangular sheet, substantially non-stretching fabric straps and fastening means form a relatively rigid liner within the motor vehicle.
Claim 2
Dependent Claim
254 words
A motor vehicle having provision to retain a passenger's extremities within the automobile in the event of a rollover comprising: a motor vehicle frame which defines a passenger compartment which includes a pair of spaced apart transverse brace members located generally above the passenger compartment; a generally rectangular sheet of a predetermined high strength substantially non-stretching fabric material, with the sheet defining front and rear edges which are disposed generally parallel to and adjacent said pair of spaced apart brace members, and opposite longitudinal side edges; a pair of high strength substantially non-stretching and continuous fabric straps of high strength fabric material attached along respective ones of the longitudinal side edges of the sheet, with each of said straps having a forward end portion which extends longitudinally beyond the front edge of the sheet, and a rear end portion which extends longitudinally beyond the rear edge of the sheet, said forward end portion of each of said fabric straps looping about one of said transverse brace members, and said rear end portion of each of said fabric straps looping about the other of said transverse brace members; fastening means attached to each of said forward and rear end portions of each of said substantially non-stretching straps and securing each of said forward and rear end portions to itself to thereby maintain the forward and rear end portions looped about the associated brace members; such that the rectangular sheet, substantially non-stretching fabric straps and fastening means form a relatively rigid liner within the motor vehicle.
