Patent attributes
A seat weight measuring apparatus having enough strength against load in a direction in which a rear side of the vehicle seat is lifted. The seat weight measuring apparatus includes a base frame with a mounting portion at the rear end side of the base frame. The mounting portion includes two stopper bolts as protective mechanisms for transmitting excessive load from a rear rail bracket to the base frame. One stopper bolt is a front (first) stopper bolt, and the other is a rear (second) stopper bolt. Therefore, the mounting portion has higher capability to withstand load than a mounting portion at the front end side of the base frame.
