Device for detecting the weight loaded onto a vehicle seat with a sensor and spring body
First Claim
1. A device for detecting the weight loaded on a vehicle seat, comprising:
- a sensor;
a spring body that connects the vehicle seat to an underbody of a corresponding motor vehicle and is connected, in a first fastening area, with a bottom rail of the vehicle seat and, in a second fastening area, to the underbody of the corresponding motor vehicle,a seat fastening screw which freely protrudes through an opening in the bottom rail of the vehicle seat, the seat fastening screw being detachably but firmly connected to the underbody; and
a retaining plate connected to the seat fastening screw, wherein the retaining plate is located above the opening of the bottom rail and straddles the openings of the bottom rail,wherein the seat fastening screw has a head and a shaft, the shaft protruding through the retaining plate via a hole, and the head being wider than the shaft and wider than the hole in the retaining plate to form an overload protection device, andwherein the sensor is a travel sensor which is disposed parallel to the seat fastening screw between the first and second fastening areas or to parts rigidly connected to the first and second fastening areas and which measures the distance of the first and second fastening areas in a direction parallel to the seat fastening screw.

Abstract
A device for detecting the weight loaded on a vehicle seat with a sensor (22) and a spring body (24) that connects the vehicle seat to an underbody (18) of a corresponding motor vehicle and is connected, in one fastening area (e.g., 28), with a bottom rail (20) of the vehicle seat on the one hand and, in another fastening area (e.g., 26), to the underbody (18) of the corresponding motor vehicle on the other hand. One of the mounting areas is provided with a bore (38) through which a seat fastening screw (30) is engaged. The sensor (22) is provided with a travel sensor which is disposed parallel to the seat fastening screw (30) between the two fastening areas (26, 28) or to these rigidly connected parts (retaining plate 60 for example) and which measures the distance of these fastening areas (26, 28) parallel to the seat fastening screw (30).
