Abstract: A seat-back frame for automotive vehicles comprising a rectangular frame of a rigid material, the frame having two upper and two lower corners, a seat belt connected to one upper corner and a tensile member obliquely extending between an upper and a diagonally lower corner of the frame to reinforce it against rhombic deformation due to external force applied in a lateral direction of the frame due to load applied to the frame, the tensile member being flexed or bowed to some extent in the rearward direction of the seat-back frame to avoid any interference with a cushioning material and cushioning springs when they are pushed backward by an occupant leaning on the seat-back and being flexible enough to straighten under tensile load.

Abstract: A seat belt structure mountable in a vehicle which provides a delayed release to the seat belt when the attached vehicle is struck from the side adjacent the seat about which the structure is mounted so as to avoid entrapment of a belted occupant of the seat. The inner side of the structure is fitted with a first seat belt, the free end of which is attachable to a second seat belt fastened adjacent an outer side of the vehicle with the fixed end of the first seat belt detachably fastened by a latch pin fixed to a lateral bar extending under the seat and joined at the outer side of the seat to a longitudinal arm. A collision force applied sidewards against the longitudinal arm and lateral bar towards the center of the vehicle moves the latch pin out of engagement with the first seat belt end so as to free the first seat belt end.

Abstract: An improved anchor for the upper portion of a shoulder harness belt in a vehicle restraint system. An anchor member having a substantial force transmitting relationship with the shoulder harness belt, preferably through a webbing relay, has a certain degree of universal type movement, and therefore allows the anchor member and the webbing relay to make appropriate movements to follow the many odd angles and twists which the webbing relay may be subjected to. The anchorage is further designed to transmit high forces between the webbing relay and the frame of the vehicle.

Abstract: A seat belt system including at least one seat belt which extends from one side of a seat to a point forward of the other side of the seat such that the seat belt extends obliquely forward from one side to the other of the seat, a tongue plate coupled to the seat belt and a buckle provided on the other side of the seat and for engagement with the tongue plate.

Abstract: An installation for the height adjustment of the upper anchoring or deflection point for the shoulder belt of a belt system in a vehicle, with individual seats adjustable in the horizontal and/or vertical direction; a transmission installation is thereby interconnected between each seat and the coordinated anchoring or deflection point which during an adjustment of the seat so displaces the anchoring or deflection point that a height position of the anchoring or deflection point is achieved which is favorable for the belt user in relation to the adjusted seat position.

Abstract: A tongueless type seat belt having a grip which is slidably affixed to the belt to protect the hand of the user when pulling out the belt, to prevent any twisting of the belt, and to be readily locked and unlocked with a tongueless buckle with a one-touch operation. On one end the belt is fixed to a portion of the car, and at the other end it is wound up in a retractor. In the intermediate portion of the belt there is a belt grip for mating with a tongueless buckle. The belt grip is slidable in the lengthwise direction of the belt and encloses the belt. The belt is made so that the front and back surfaces are readily distinguishable from each other.

Abstract: Mechanism for retracting a vehicle seat belt and locking the belt against extension includes a track mounted on the vehicle body and a belt carriage mounted on the track for movement in the belt extending and retracting directions. A locking pawl is mounted on the belt carriage and is selectively actuatable to a locked position engaging teeth on the track to lock the belt carriage against belt extending movement. A spring biases the carriage in the belt retracting direction. An actuating element extends alongside the track and is mounted for rotary movement into engagement with the locking pawl to move the locking pawl to the locked position. A pendulum supports the actuating element in a normal position and rotates the actuating element in response to a sensed condition of vehicle deceleration to actuate the locking means and thereby lock the carriage against belt extending movement along the track.
