Vehicle seat
First Claim
1. A seat including a seat belt fastened to an anchor, wherein the anchor is located on one side of a rear portion of the seat, the seat comprising;
- a first load sensor attached to the seat in the vicinity of the anchor to detect load and generate a first detection value representing the load detected by the first load sensor;
a second load sensor attached to the seal at a side opposite to the first load sensor to detect load and generate a second detection value representing the load detected by the second load sensor; and
a control unit connected to the first and second load sensors, wherein the control unit determines whether a child restraint apparatus is present based on the first and second detection values.

Abstract
A vehicle seat that detects a child restraint apparatus, which is attached to the seat by a seat belt, for operation of an air bag. A first load sensor is attached to one side of the seat to detect load and generate a first detection value. A second load sensor is attached to the seat at an opposite side of the seat to detect load and generate a second detection value. A control unit is connected to the first and second load sensors and determines whether the child restraint apparatus is present based on the first and second detection values.

12. A method for detecting whether a child restraint apparatus is fastened to a seat by a seat belt that is fastened to an anchor, wherein the anchor is located on one side of a rear portion of the seat, and wherein the seat includes a first load sensor attached to the seat in the vicinity of the anchor to detect load and generate a first detection value representing the load detected by the first load sensor, a second load sensor attached to the seat at a side opposite to the first load sensor to detect load and generate a second detection value representing the load detected by the second load sensor, the method comprising:
-
comparing the first and second detection values;
obtaining a difference between the first and second detection values;
comparing the difference with a predetermined rear differential reference value; and
determining that the child restraint apparatus is present when the second detection value is greater than the first detection value and the difference is greater than the rear differential reference value. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
