Abstract
Abstract A seat safety harness having a pair of shoulder-lap straps arranged to pass over the shoulders of the seat occupant, each strap having a first end adapted to be reeled onto the springloaded spool of a first retraction reel assembly of the inertia type mounted substantially behind the seat occupant, and having a second end attached to one of the attachment means located substantially below the lap of the seat occupant, at least one of the second ends of the straps being reeled onto a spring-loaded spool of a second retraction reel assembly of the inertia type that constitutes at least one of the attachment means. Quickrelease buckles are fixed to the straps and are selectively connectable to provide two shoulder strap portions and a lap strap portion. The spring loading of the spool of the second retraction reel assembly is greater than the spring loading of the spool of the first retraction reel assembly so that the harness is self-adjusting when worn by the occupant and is selfstoring when not in use. Strap guides slidably receive the straps between the second retraction reel assembly and the buckles so that the buckles engage the guides to limit reel takeup on the associated spool before the straps have unreeled from the spool of the first retraction reel assembly. In one embodiment, a pair of spring-loaded spools of the second retraction reel assembly are mounted, one on each side of the seat, the second strap ends extending down over opposite seat sides for connection to such spools. In another embodiment, the spools of the second retraction reel assembly are mounted at the rear of the seat, the second strap ends extending down between the seat portion and back portion of a seat for connection to the spools.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
A seat safety harness, comprising: a. a first retraction reel means of the inertia type mounted substantially behind the seat occupant, b. a pair of attachment means located substantially below the lap of the seat occupant, at least one of the attachment means including a second retraction reel means of the inertia type, c. a pair of shoulder-lap straps arranged to pass over the shoulders of the seat occupant, each strap having a first end adapted to be reeled onto the first retraction reel means, and having a second end attached to one of the attachment means, at least one of the second ends being reeled onto the second retraction reel means, d. connector means fixed to the straps and selectively connectable to provide two shoulder strap portions and a lap strap, and e. the spring loading of the second retraction reel means being greater than the spring loading of the first retraction reel means to urge the straps toward the second retraction reel means so that the harness is self-adjusting when worn by the occupant, the lap strap portion being held firmly across the occupant''3 lap, and so that the harness is self-storing when not in use.
Claim 2
Dependent Claim
198 words
A seat safety harness, comprising: a. a first retraction reel means of the inertia type mounted substantially behind the seat occupant, b. a pair of attachment means located substantially below the lap of the seat occupant, at least one of the attachment means including a second retraction reel means of the inertia type, c. a pair of shoulder-lap straps arranged to pass over the shoulders of the seat occupant, each strap having a first end adapted to be reeled onto the first retraction reel means, and having a second end attached to one of the attachment means, at least one of the second ends being reeled onto the second retraction reel means, d. connector means fixed to the straps and selectively connectable to provide two shoulder strap portions and a lap strap, and e. the spring loading of the second retraction reel means being greater than the spring loading of the first retraction reel means to urge the straps toward the second retraction reel means so that the harness is self-adjusting when worn by the occupant, the lap strap portion being held firmly across the occupant''3 lap, and so that the harness is self-storing when not in use.
Claim 3
Dependent Claim
189 words
A seat safety harness, comprising: a. a first retraction reel means of the inertia type mounted substantially behind the seat occupant, the first retraction reel means including a first rotatable strap-receiving spool means to receive a strap and reel it automatically onto the first spool means under spring action, b. a second retraction reel means of the inertia type mounted substantially below the lap of the seat occupant, the second retraction reel means including a second rotatable strap-receiving spool means to receive a strap and reel it automatically onto the second spool means under spring action, c. a pair of shoulder-lap straps arranged to pass over the shoulders of the seat occupant, each strap having a first end adapted to be reeled onto the first spool means, and having a second end adapted to be reeled onto the second spool means, and d. the spring loading of the second spool means being greater than the spring loading of the first spool means to urge the straps toward the second spool means so that the harness is self-adjusting when worn by the occupant and is self-storing when not in use.
Claim 4
Dependent Claim
189 words
A seat safety harness, comprising: a. a first retraction reel means of the inertia type mounted substantially behind the seat occupant, the first retraction reel means including a first rotatable strap-receiving spool means to receive a strap and reel it automatically onto the first spool means under spring action, b. a second retraction reel means of the inertia type mounted substantially below the lap of the seat occupant, the second retraction reel means including a second rotatable strap-receiving spool means to receive a strap and reel it automatically onto the second spool means under spring action, c. a pair of shoulder-lap straps arranged to pass over the shoulders of the seat occupant, each strap having a first end adapted to be reeled onto the first spool means, and having a second end adapted to be reeled onto the second spool means, and d. the spring loading of the second spool means being greater than the spring loading of the first spool means to urge the straps toward the second spool means so that the harness is self-adjusting when worn by the occupant and is self-storing when not in use.
Claim 5
Dependent Claim
63 words
A seat safety harness as defined in claim 2, in which: e. connector means are fixed to the straps and selectively connectable to provide two shoulder strap portions and a lap strap portion, the greater spring loading of the second spool means holding the lap strap portion firmly across the lap of the occupant by urging said portion toward said second spool means.
Claim 6
Dependent Claim
44 words
A seat safety harness as defined in claim 2, in which: e. limit means coact with the straps to limit reel takeup on the second spool means before the straps have unreeled from the first spool means under pull from the second spool means.
Claim 7
Dependent Claim
105 words
A seat safety harness as defined in claim 2, in which: e. connector means are fixed to the straps and selectively interconnectable to provide two shoulder strap portions and a lap strap portion, the greater spring loading of the second spool means holding the lap strap portion firmly across the lap of the occupant, by urging said portion toward said second spool means, and f. strap guides selectively receive the straps between the second spool means and the connector means, the connector means engaging the guides to limit reel takeup on the second spool means before the straps are unreeled from the first spool means.
Claim 8
Dependent Claim
60 words
A seat safety harness as defined in claim 2, in which: e. the second spool means includes a pair of spring loaded spools mounted on each side of the Seat and having a combined spring loading greater than the spring loading of the first spool means, the second strap end extending over the seat sides for connection to said spools.
