Belt lock for vehicle safety belt has functional part that lies in different position with belt lock closed so switch has different state in lock closed position than in lock open position

摘要

The device has a locking mechanism for connection to a belt strap with an insertion channel for a belt tongue, a lock element, an actuating mechanism, a release mechanism and a switch device for generating an electrical state signal. The switch device has an encapsulated mechanical switch(s) with an actuation element in the path of a locking mechanism part that lies in another position with the belt lock closed, giving alternative switch states. The device has a locking mechanism for connection to a belt strap with an insertion channel for a belt tongue, a lock element for engagement with an aperture in the tongue, an actuating mechanism for the lock element, a release mechanism and a switch device for generating an electrical signal representing the closed state of the belt lock. The switch device contains at least one mechanical switch (14) encapsulated against air and moisture with an actuation element (16) in the path of motion of a functional part (9) of the locking mechanism (7) that lies in another position with the belt lock closed so the switch has a different state in the lock closed position than in the lock open position.
