Abstract
Abstract A three-point passive seat belt system includes a continuous-loop restraint belt having upper and lower ends attached to the door and a control belt having an outboard end attached to a junction ring which encircles the continuous-loop belt to define lap and shoulder belt portions. An inboard retractor winds the control belt when the door is closed to establish the lap and shoulder belt portions respectively across the lower and upper torso of the occupant. The outboard end of the lap belt is attached to the door by a resilient anchor strap and disconnect buckle located substantially forward on the door to permit limited forward excursion of the occupant lower torso simultaneous with limited forward excursion of the upper torso to maintain the occupant in a more vertically upright position to thereby limit forward rotational excursion of the head. An auxiliary buckle is mounted on the vehicle body adjacent the outboard side of the passenger seat and more rearwardly than the doormounted disconnect buckle for engagement by the lap belt to restrain a child occupant against forward excursion of the lower torso. The lap belt is also engaged with the auxiliary buckle for restraint of a child seat so that the lap belt remains disposed in restraining position across the child seat when the door is opened.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
185 words
In combination, a vehicle body having a seat located laterally adjacent a door hinged for movement between open and closed positions; a shoulder belt having an outboard end mounted on the upper rear corner of the door and an inboard end; a lap belt having an outboard end and an inboard end; a disconnect buckle adapted to attach the lap belt outboard end on the door and including a first buckle component mounted on the door and a second buckle component mounted on the outboard lap belt end; a retractor means mounted on the vehicle body inboard the occupant seat for winding the lap and shoulder belts to occupant restraining positions when the door is closed and permitting outward and forward movement of the lap and shoulder belts with the door to an occupant access position when the door is opened; and a third buckle component mounted on the vehicle body outboard the seat and generally adjacent the door-mounted first buckle component for selective coupling with the belt-mounted second buckle component to adapt the restraint system for restraint of a child or a child seat.
Claim 2
Dependent Claim
185 words
In combination, a vehicle body having a seat located laterally adjacent a door hinged for movement between open and closed positions; a shoulder belt having an outboard end mounted on the upper rear corner of the door and an inboard end; a lap belt having an outboard end and an inboard end; a disconnect buckle adapted to attach the lap belt outboard end on the door and including a first buckle component mounted on the door and a second buckle component mounted on the outboard lap belt end; a retractor means mounted on the vehicle body inboard the occupant seat for winding the lap and shoulder belts to occupant restraining positions when the door is closed and permitting outward and forward movement of the lap and shoulder belts with the door to an occupant access position when the door is opened; and a third buckle component mounted on the vehicle body outboard the seat and generally adjacent the door-mounted first buckle component for selective coupling with the belt-mounted second buckle component to adapt the restraint system for restraint of a child or a child seat.
Claim 3
Dependent Claim
256 words
In combination, a vehicle body having a seat located laterally adjacent a door hinged for movement between open and closed positions; a shoulder belt having an outboard end mounted on the upper rear corner of the door and an inboard end; a lap belt having an outboard end and an inboard end; a disconnect buckle adapted to attach the lap belt end on the door and including a first buckle component mounted on the door and a second buckle component mounted on the outboard lap belt end, said first buckle component being located relatively forward on the vehicle door whereby the lower torso of the restrained occupant is permitted to move substantially forwardly in unison with forward movement of the upper torso into the shoulder belt to prevent forward pivoting movement of the upper torso and thereby limit forward rotation of the occupant head; a retractor means mounted on the vehicle body inboard the occupant seat for winding the lap and shoulder belts to occupant restraining positions when the door is closed and permitting outward movement of the lap and shoulder belts with the door to an occupant access position when the door is opened; and a third buckle component mounted on the vehicle body rearwardly of the door-mounted first buckle component for selective coupling with the belt-mounted second buckle component to adapt the restraint system for restraint of a child whereby the lower torso is restrained in a rearward position against forward movement to effectively restrain the child against forward movement beneath the shoulder belt.
Claim 4
Dependent Claim
256 words
In combination, a vehicle body having a seat located laterally adjacent a door hinged for movement between open and closed positions; a shoulder belt having an outboard end mounted on the upper rear corner of the door and an inboard end; a lap belt having an outboard end and an inboard end; a disconnect buckle adapted to attach the lap belt end on the door and including a first buckle component mounted on the door and a second buckle component mounted on the outboard lap belt end, said first buckle component being located relatively forward on the vehicle door whereby the lower torso of the restrained occupant is permitted to move substantially forwardly in unison with forward movement of the upper torso into the shoulder belt to prevent forward pivoting movement of the upper torso and thereby limit forward rotation of the occupant head; a retractor means mounted on the vehicle body inboard the occupant seat for winding the lap and shoulder belts to occupant restraining positions when the door is closed and permitting outward movement of the lap and shoulder belts with the door to an occupant access position when the door is opened; and a third buckle component mounted on the vehicle body rearwardly of the door-mounted first buckle component for selective coupling with the belt-mounted second buckle component to adapt the restraint system for restraint of a child whereby the lower torso is restrained in a rearward position against forward movement to effectively restrain the child against forward movement beneath the shoulder belt.
Claim 5
Dependent Claim
277 words
A restraint system for a motor vehicle body having an occupant seat located laterally adjacent a door hingedly mounted for movement between open and closed positions and a child seat adapted for mounting on the occupant seat for seating a child, comprising: a continuous-loop belt having first and second outboard ends mounted on the door for movement with the door between the open and closed positions; a disconnect buckle adapted to attach the first belt end on the door and including a first buckle component mounted on the door and a second buckle component mounted on the first belt end; a control belt retractably mounted inboard of the occupant seating position; a junction ring attached to the control belt and slidably encircling the continuous-loop belt to divide the continuous-loop belt into a lap belt portion and a shoulder belt portion, said junction ring moving from a position generally inboard the seat when the door is closed to a position generally outboard and forward the seat when the door is opened so that door movement automatically moves the lap and shoulder belt portions between an occupant restraining position when the door is closed and an occupant access position when the door is open; and a third buckle component mounted on the vehicle body generally adjacent the door-mounted first buckle component for selective coupling with the belt-mounted second buckle component to adapt the restraint system for restraint of the child seat whereby when the door is opened only the second end of the continuous-loop belt moves outboard and forward with the door so that the lap belt and control belt remain disposed in restraining position over the child seat.
