Attachment structure of passenger distinguishing apparatus

An attachment structure of a passenger distinguishing apparatus, comprising:

• a weight detection sensor which detects a weight of a passenger seated in the vehicle seat;
• a lower bracket provided at a lower end of the weight detection sensor;
• an upper bracket provided at an upper end of the weight detection sensor;
• at least one nut that is threaded with at least one of an upper end part and a lower end part of the weight detection sensor such that the weight detection sensor is fixed to at least one of the lower bracket and the upper bracket;
• and
• a damper which absorbs an assembling tolerance of the weight detection sensor and is concentrically received at the upper end of the weight detection sensor, the damper comprising a damper body at a lower end thereof and a damper extension at an upper end thereof, wherein the damper body and the damper extension each directly contact the upper bracket, and the upper bracket is placed between the nut and the damper body.

An attachment structure of a passenger distinguishing apparatus, comprising:

• a lower bracket connected to a floor of the vehicle;
• an upper bracket connected to the vehicle seat;
• a weight detection sensor to detect a weight of a passenger seated in the vehicle seat;
• at least one nut that is threaded with at least one of an upper end part and a lower end part of the weight detection sensor such that the weight detection sensor is fixed to at least one of the lower bracket and the upper bracket;
• a sleeve concentrically received by and directly contacting the weight detection sensor, the sleeve comprising an upper sleeve portion and a lower sleeve portion having a groove formed in an upper surface thereof and having sidewalls, the lower sleeve portion having a circumference greater than the circumference of the upper sleeve portion;
• and
• a damper provided at the groove and concentrically disposed between the sleeve and the upper bracket and directly contacting the sleeve, the upper bracket, and the nut.
