Passenger's weight measurement device for vehicle seat and attachment structure for load sensor
First Claim
1. A passenger'"'"'s weight detecting device, comprising:
- a movable rail member;
a side frame member;
a load sensor comprising a rod portion and operably connected between the movable rail member and the side frame member via a through-hole; and
an elastic member around the rod portion in the through-hole, comprising a varied-diameter portion in which an outer diameter of the elastic member is varied along a shaft line direction of the rod portion, and configured to reduce an initial load that is applied to the load sensor and generated by distortion.

Abstract
A passenger'"'"'s weight measurement device for a vehicle seat, capable of suppressing generation of an initial load, has a pair of slide rails extending in parallel and fixed to the vehicle floor, and a pair of side frames that support the seat and are disposed above the pair of slide rails. Load cells are disposed between the pair of the slide rails and the pair of the side frames. A set of first connection frames for connecting both ends of the pair of side frames extend in parallel to be perpendicular to the pair of side frames. Second and third connecting frames connect middle parts of the pair of slide rails so as to be perpendicular to the slide rails. The pair of the slide rails and the second and a third connecting frames constitute an H-shaped frame. The load cells include an elastic member having a varied-diameter portion.
