Sensor arrangement for detecting seat suitable for resting back, has two sensors in backrest of seat, where sensors detect whether back abuts, thigh overlies on seat and buttock overlies on back rest at sufficient far direction

摘要

The sensor arrangement has two sensors (1) e.g. pressure-sensitive sensors, provided in a backrest (R) of a seat (S). Two sensors (2) are provided in the seat for a buttock-area. Two sensors (3) are provided in the seat at a thigh area. The sensors cover the entire seat. The sensors detect whether the back abuts, the thigh overlies on the seat, and the buttock overlies on the back rest at a sufficient far direction, and whether the left of/right load of the seat /backrest is symmetrical.
