Abstract

A seat belt device allowing easy connection of a lap anchor fixed to one end of a seat belt relative to a vehicle body or the like even when a seat weight sensor is installed below a vehicle seat. The seat weight sensor and the vehicle seat are fixed to a vehicle body floor. A hitch member is attached to the seat weight sensor via a mounting bracket by a bolt. A lap anchor is fixed to one end of a seat belt. By locking the lap anchor to the hitch member, the seat belt is connected to the seat weight sensor. In this manner, the seat belt can be easily connected to the vehicle body just by locking the lap anchor to the hitch member.

Claims

a seat belt for restraining and protecting an occupant sitting on a vehicle seat, the seat belt including a lap anchor at one end of the seat belt,

wherein a seat weight sensor for sensing a load applied to the vehicle seat is installed below the vehicle seat, the seat weight sensor including a mounting bracket extending away from a load sensing portion of the seat weight sensor,

wherein a slide bar is attached to the mounting bracket so that the slide bar is fixed relative to the seat weight sensor, wherein one of the slide bar and the mounting bracket includes an elongated hole that facilitates the alignment and connection of the slide bar to the mounting bracket,

wherein the lap anchor is slidably connected to the slide bar, and

wherein the mounting bracket has side walls and a supporting collar is located between the side walls.

2. The system of claim 1, further comprising a second collar located between one of the side walls and the slide bar.
