On-board person load sensor

摘要

An occupant load sensor ( 10 ) is fixed to a bracket ( 48 ) via a sleeve ( 60 a) of a collar ( 60 ) arranged in an outer periphery of a thread ( 32 ) of a bolt portion ( 30 ), and a bush ( 62 ) interposed between the sleeve ( 60 a) and a through hole ( 48 a) of the bracket ( 48 ). Accordingly, a slight movement is allowed between the bolt portion ( 30 ) and the bracket ( 48 ) on the basis of gaps formed between the thread ( 32 ) and the sleeve ( 60 a) and between the sleeve ( 60 a) and the bush ( 62 ), and it is possible to cancel a force applied from the other directions than a vertical direction. Therefore, a load from the seat side is applied in the vertical direction and it is possible to accurately detect.
