Load sensing device
First Claim
1. A load sensing device, which includes a load detecting device adapted to a seat and outputting a load signal in response to a strain generated at the load detecting device and which detects a load applied to the seat on the basis of the load signal outputted from the load detecting device, the load sensing device comprising;
- a determining means determining whether the seat is in an occupied state or in a vacant state on the basis of a magnitude relationship between the detected load and a threshold value;
a collision detecting means detecting a shock generated when a vehicle collides; and
a memorizing means storing therein a diagnosis information indicating a necessity of a zero-point adjustment of the load detecting device to be executed in a case where the seat is determined to be in the occupied state by the determining means when the shock is detected by the collision detecting means, and indicating that the zero-point adjustment does not need to be executed in a case where the seat is determined to be in the vacant state by the determining means when the shock is detected by the collision detecting means.

Abstract
A load sensing device, which includes a load detecting device adapted to a seat and outputting a load signal in response to a strain generated at the load detecting device and which detects a load applied to the seat on the basis of the load signal, includes a determining device determining whether the seat is in an occupied state or in a vacant state based on a magnitude relationship between the load and a threshold value, a collision detecting device detecting a shock generated when a vehicle collides, an alarming device alarming that the shock is detected, and a memorizing device storing a diagnosis information indicating whether or not a zero-point adjustment of the load detecting device needs to be executed in response to a determination result of a state of the seat in the case where the shock is detected by the load detecting member.

8. A seat load sensing device comprising;
-
determining means for determining whether a seat mounted of a vehicle is in an occupied state or in a vacant state on the basis of a comparison between a strain of the seat that is indicative of a load applied to the seat and a threshold value; collision detecting means for detecting a shock generated upon collision of the vehicle with another structure; and memorizing means for storing therein a diagnosis information indicating a necessity of a zero-point adjustment of the load detecting device to be executed in a case where the seat is determined to be in the occupied state by the determining means when the shock is detected by the collision detecting means, and indicating that the zero-point adjustment does not need to be executed in a case where the seat is determined to be in the vacant state by the determining means when the shock is detected by the collision detecting means. - View Dependent Claims (9, 10, 11, 12, 13, 14, 17, 18)
