Title: Motor vehicle seat belt construction - has one anchor point fitted with strap slide-blocking and delaying eyelet fitting with wavy edge
Inventor: DEPMEYER LOTHAR
IPC: B60R22/30
Filed: 1977-09-14
Abstract: A seat belt anchor point fitting is of the eyelet type, which in case of a sudden deceleration of the vehicle would prevent sliding movement of the strap through the eyelet. The seat belt system consists of anchor point (8) with lock assembly (3) the locking plate of which is fitted to an eyelet (6). From the lock assembly abdominal strap (10) leads to fixed anchor point (5) and diagonal strap (2) to fixed anchor point (1). In case of impacts it is known that the upper part of the body slumps forward with a greater force than the lower part. Consequently the diagonal strap is tensioned causing a slipping motion in the eyelet (6) hereby shortening the abdominal strap. To prevent this the edge of the eyelet in contact with the strap is not straight but wavy. The extremely tensioned strap deforms laterally over the wavy edge, hereby increasing the area of contact between strap and edge and consequently increasing friction between the two elements resulting in slowing down or completely blocking the sliding movement.

Filed: 1978-04-06
Abstract: A circuit arrangement for feeding a circuit (8) and a load (1) controlled by the circuit pulse by pulse, for example a clock timer. An input voltage (Ue) feeds the load (1) via a voltage divider (23, 24, 25, 26) and a line (4a) feeds a NiCad cell (5) via a diode (9) and a series resistor (10), for maintaining operation in the event of voltage failure, in which case a buffer capacitor (18) charged up by the NiCad cell (5) during the pulse intervals then supplies the pulse energy. The NiCad cell (5) stabilizes the feed voltage at connection (7) of the circuit (8). In the event of a short circuit of the NiCad cell (5), the feed voltage for the circuit (8) is picked up at the voltage divider consisting of a resistor (21) and a diode (19) whilst in the case of an interruption, a stabilizing diode (20), the series circuit of which with the diode (19) is connected to the voltage of the line (4a) stabilizes the feed voltage of the circuit (8). GaAsP light-emitting diodes are used as stabilizing diodes (20, 26), one (20) of which is used for visually indicating a short circuit of the NiCad cell (5) whilst its interruption can be indicated by a further light-emitting diode (32). <IMAGE>
