Abstract
Abstract A restraint device for protecting the occupant of the sleeper bunk of a vehicle cab includes a web-like harness, constructed of flexible straps, that is supported within and attached to the cab structure so as to provide a vertical leg extending across the open front side of the bunk and a horizontal leg extending over the bunk to the rear cab structure. This harness arrangement transmits a portion of any forwardly directed forces received by the harness to the rear cab structure, thus reducing the horizontal load imposed on the supports for the vertical leg. Quick release buckles are provided in the harness to allow the occupant ready egress from the bunk. The harness also converts into a hammock-type storage area when the bunk is not in use.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
143 words
An occupant restraint device adapted to be positioned across the open front side of a sleeper bunk in a vehicle cab comprising: an elongated flexible harness, means securing one free end of the harness to the cab structure adjacent the front side of the bunk, means securing the other free end of the harness to the cab structure at the rear side of the bunk and means attached to the cabin structure for supporting the harness at a point intermediate its free ends so as to form a generally vertical harness leg extending across the open front side of the bunk and a generally horizontal harness leg extending from the vertical leg to the rear cabin structure, whereby forces received by the vertical leg in preventing the occupant from being dislodged from the bunk are transmitted in part to the rear cabin structure.
Claim 2
Dependent Claim
143 words
An occupant restraint device adapted to be positioned across the open front side of a sleeper bunk in a vehicle cab comprising: an elongated flexible harness, means securing one free end of the harness to the cab structure adjacent the front side of the bunk, means securing the other free end of the harness to the cab structure at the rear side of the bunk and means attached to the cabin structure for supporting the harness at a point intermediate its free ends so as to form a generally vertical harness leg extending across the open front side of the bunk and a generally horizontal harness leg extending from the vertical leg to the rear cabin structure, whereby forces received by the vertical leg in preventing the occupant from being dislodged from the bunk are transmitted in part to the rear cabin structure.
Claim 3
Dependent Claim
38 words
An occupant restraint device according to claim 1 further comprising quick-release means associated with the harness for allowing rapid disassembly thereof by the bunk occupant, thereby permitting ready escape from the bunk in the event of an emergency.
Claim 4
Dependent Claim
33 words
An occupant restraint device according to claim 2 wherein the quick-release means comprises one or more quick-release buckles included in the vertical leg of the harness for rEleasably connecting together two segments thereof.
Claim 5
Dependent Claim
52 words
An occupant restraint device according to claim 1 wherein the vertical leg of the harness includes a plurality of straps interconnected to form a web assembly, and wherein the horizontal leg includes at least one strap that extends through the intermediate harness supporting means and is connected to the vertical web assembly.
Claim 6
Dependent Claim
35 words
An occupant restraint device according to claim 4 further comprising quick-release means interposed in the vertical leg for releasably connecting at least the one strap included in the horizontal leg to the vertical web assembly.
Claim 7
Dependent Claim
70 words
An occupant restraint device according to claim 1 wherein the free end of the vertical harness leg secured to the cab structure is the lower end, the free end of the horizontal harness leg is secured to the rear cabin structure at a point above the bunk, and the intermediate harness supporting means is attached to the cab roof structure at a point spaced forwardly of the rear cab structure.
Claim 8
Dependent Claim
95 words
An occupant restraint device according to claim 6 further comprising means, carried by the vertical harness leg adjacent the lower end thereof, adapted for engagement with cooperating means associated with the means for securing the horizontal harness leg to the rear cab structure, and wherein the means for securing the lower end of the harness vertical leg to the cab structure is releasable, whereby the harness vertical leg may be extended rearwardly beneath the harness horizontal leg and secured to the cooperating means on the rear cab structure so as to provide a hammock-type area.
Claim 9
Dependent Claim
49 words
An occupant restraint device according to claim 6 further comprising quick-release means included in the harness vertical leg adjacent the upper end thereof for allowing rapid disassembly of the harness by an occupant of the bunk, thereby permitting ready escape by the occupant in the event of an emergency.
