Abstract
A seat belt device in an automotive seat, which comprises a seat belt extending from a part of the automobile to a floor of the same for restraining a passenger to the seat, and a seat belt guide provided at one upper corner portion of the seat back of the seat. The seat belt guide includes a guide anchor through which the seat belt slidably passes, and a drive mechanism for causing such through guide anchor to be moved in a vertical direction along the longitudinal direction of the seat back. Thus, the initial point at which the seat belt begins to approach a passenger may be set at a desired level via the guide anchor, thereby adapting the seat belt to better fit, and hence better restrain the passenger's trunk to the seat, irrespective of his or her individual physical differences and/or inclination of the seat back.
Claims6
A seat belt device in an automotive seat for an automobile, in which the seat includes a seat cushion and a seat back having an upper corner portion and means to provide the seat back to be inclinable relative to said seat cushion, said seat belt device comprising:

- and
- a seat belt guide means provided at said upper corner portion of said seat back, said seat belt guide means including:
- a drive mechanism which is disposed in said seat back at a location corresponding to said upper corner portion of said seat back, said drive mechanism including:
- (a) a mounting means;
- (b) a drive means for causing said mounting means to be moved in a vertical direction along a longitudinal direct on of said seat back;
- and
- (c) a motor for causing operation of said drive means, and
- a guide anchor which extends from said seat back and connected to said mounting means of said drive mechanism, such that said anchor is located at the same location with that of said drive mechanism at said upper corner portion of said seat back, wherein said seat belt slidably passes through said guide anchor;
- wherein operation of said mechanism causes said guide anchor to be displaced in said vertical direction, so that said seat belt may be anchored at a desired initial point in said upper corner of said seat back and thus the initial point of said seat belt with respect to the seat back front said anchor to the automobile may be varied to accommodate the fit of the seat belt to passengers of different sizes when the seat is reclined.
