1. A seat weight measuring apparatus comprising:
- a support body one end of which is fixed in position relative to a vehicle body and the other end of which is configured to be displaced in response to a load from a vehicle seat side;
a held body which has a shape retaining property and is connected to the other end of the support body;
wherein the support body includes a held body facing portion that faces a tip of the held body such that a distance from the tip of the held body to the held body facing portion in the vertical direction of a vehicle body is smaller than a distance from the tip of the held body to the held body facing portion in the horizontal direction; and
wherein a magnetism detecting device is disposed on the tip of the held body, wherein load from the vehicle seat side is measured by detecting a variation in the strength of a magnetic field detected by the magnetism detecting device, wherein the variation results from the displacement of the support body corresponding to the load from the vehicle seat side.

Abstract
A seat weight measuring apparatus includes a support body one end of which is fixed in position relative to a vehicle body and the other end of which is displaced corresponding to a load from a vehicle seat side. The apparatus includes a permanent magnet which is disposed at one end of the support body and a held body which has a shape retaining property and is held by the other end of the support body, and a detector which is disposed on a tip of the held body to face the permanent magnet with a space therebetween.

8. A seat weight measuring apparatus comprising:
-
a support body, wherein the rigidity of the support body in the vertical direction of a vehicle body is less than the rigidity of the support body in the horizontal direction, and wherein one end of the support body is fixed relative to the vehicle body and the other end of the support body is configured to be displaced in response to a load from a vehicle seat side;
a held body which has a shape retaining property and is connected to the other end side of the support body;
a held body facing portion for detecting displacement of the support body which is formed in the support body to face a tip of the held body; and
a magnetism detecting device disposed on the tip of the held body, wherein load from the vehicle seat side is measured based on variation in strength of magnetic field resulting from a variation in the distance between the held body facing portion and the tip of the held body, the variation corresponding to displacement of the support body resulting from the load from the vehicle seat side. - View Dependent Claims (9, 10)

11. A seat weight measuring apparatus comprising:
-
a support body one end of which is fixed in position relative to a vehicle body and the other end of which is displaced corresponding to a load from a vehicle seat side;
a cable held at its middle position by the other end of the support body;
a cable facing portion for detecting displacement of the support body which is formed in the support body to face a tip of the cable, the cable facing portion comprising a permanent magnet; and
a magnetic detector disposed on the tip of the cable, wherein the magnetic detector has a detection range only in the vertical direction. - View Dependent Claims (12, 13, 14)
