A four-point seat belt device includes two shoulder belts to press the shoulders of a passenger sitting in a seat, a restraint element extending between the two shoulder belts, and a driving unit arrangement to perform winding of the belts upon detection of a collision.
Claims21
A four-point seat belt device comprising:
- first and second shoulder belts;
- a first tongue plate at an extracting end region of the first shoulder belt, and a second tongue plate at an extracting end region of the second shoulder belt;
- a first buckle at an extracting end region of a first front belt for latching with the first tongue plate, and a second buckle at an extracting end region of a second front belt for latching with the second tongue plate;
- at least one restraint element extending between the first and second shoulder belts;
- and
- a driving unit arrangement for performing belt winding, in response to a collision detection signal, to restrain a passenger by retracting the first and second shoulder belts and retracting the first and second front belts.
