US 2011/0084525 A1 · PASSENGER'S WEIGHT MEASUREMENT DEVICE FOR VEHICLE SEAT

Abstract

To provide a passenger's weight measurement device for a vehicle seat which can be assembled to prevent the occurrence of the initial deformation and the initial load. The passenger's weight measurement device comprises a pair of left and right fixed lower rails, a pair of movable upper rails disposed to be movable in a front-and-rear direction on each of the fixed lower rails, load sensors fixed on an upper surface of the left movable upper rail, load sensors mounted on the movable upper rail to be movable in a left-and-right direction with respect to the right movable upper rail, and a rectangular frame mounted on the load sensors. Mounting holes are formed on the rectangular frame, and rods are inserted into the mounting holes from bottom up. The rods are engaged with nuts.

A vehicle seat comprising a passenger's weight measurement device, comprising:

right and left rail members, each of the right and left rail members comprising a fixed rail that is fixable to a vehicle and a movable rail that is disposed to be movable in a longitudinal direction of the fixed rail;
a first load sensor that is mounted to at least one of the right and left rail members;
a second load sensor that is mounted to at least one of the right and left rail members,
a first attachment portion for attaching the first load sensor;
and
a second attachment portion for attaching the second load sensor,
wherein the first load sensor is disposed more forwardly than the second load sensor,
wherein a first projecting wall projecting in an up-and-down direction is formed on a front side of the first attachment portion so as to form the first projecting wall and the first attachment portion as one member, and
wherein a second projecting wall projecting in the up-and-down direction is formed on a rear side of the second attachment portion so as to form the second projecting wall and the second attachment portion as one member.
