Abstract
A system for warning an effective restraint limit of a seat belt, comprising a seat slidably adjustable in a to-and-fro direction and tiltably adjustable, a seat belt for restraining an occupant seated on the seat, a sensor device for detecting an effective restraint limit of the seat belt, a notice device for notifying the occupant of the result as detected by the sensor device, characterized in that the effective restraint limit of the seat belt as detected by the sensor device is a reclining angle corresponding to a position of the seat as slidably adjusted.
Claims4
A system for warning an effective restraint limit of a seat belt, comprising a seat slidably adjustable on a support in a to-and-fro direction a backrest that is and tiltably adjustable, a seat belt lap and shoulder assembly for restraining an occupant seated on said seat, sensor means for detecting an effective restraint limit of said seat belt, and notice means for notifying the occupant of a result as detected by said sensor means, wherein that the effective restraint limit of said seat belt assembly as detected by said sensor means is an angle of said backrest corresponding to a position of said seat as slidably adjusted.
A system for warning an effective restraint limit of a seat belt, comprising:
- support rails disposed in a vehicle,
- a seat slidable on said support rails and including a seat cushion and a backrest tiltably connected to said seat cushion;
- a rotary member body rotatable coaxially and independently of said backrest;
- a reel portion connected to said rotary member body through a reduction mechanism and disposed coaxially of said backrest;
- a wire having one end wound around said reel portion and the other end fixed to said rail, said reel portion being rotated by said wire when said seat is slidably moved on said rails;
- two resilient members extending from said rotary member body and made of an electrically conductive material;
- pin means extending from said seat cushion and positioned in such a manner that said two resilient members are brought into contact with one another when said seat reaches an effective restraint limit of a seat belt;
- and
- means for applying a voltage to said two resilient members to cause a current to flow through said two resilient members when bought into contact with one another and providing a warning.
