Abstract
A vehicle seat and occupant restraint arrangement for a vehicle is provided which, in a preferred embodiment, includes a seat pan member having forward and rearward ends, a seat back joined with the seat pan rearward end, the seat back having an upper end, a D-ring joined to the seat back generally adjacent the upper end of the seat back, an anchor being generally fixed with respect to the vehicle, an occupant restraint belt with a first end operatively associated with the anchor, the restraint belt being threaded through the D-ring, and a lock plate mounted on legs of the D-ring to catch the occupant restraint belt upon sudden excessive acceleration of the vehicle in the forward direction to tension the restraint belt between the D-ring and the anchor to minimize angular movement of the seat back rearwardly.
Claims2
A vehicle seat and occupant restraint arrangement for a vehicle having forward and rearward ends, the arrangement comprising:
- a seat pan member having forward and rearward ends;
- a seat back joined with the seat pan rearward end, the seat back having an upper end;
- a D-ring joined to the seat back generally adjacent the upper end of the seat back;
- a first anchor means including a retractor which locks upon experiencing an excessive forward acceleration of the vehicle being generally fixed with respect to the vehicle;
- a shoulder harness with a first end operatively associated with the first anchor means, the shoulder harness being threaded through the D-ring, and the shoulder harness being normally freely passable through the D-ring;
- and
- inertia locking means in the D-ring to cause the D-ring to catch the shoulder harness upon sudden excessive acceleration of the vehicle in the forward direction to tension the shoulder harness between the D-ring and the anchor means to minimize angular movement of the seat back rearwardly.
