ABSTRACT:
A buckle device is provided, for use with a seatbelt system of a vehicle, into which a tongue plate is inserted for engagements with a lock member, and which has in addition to the lock member with which the tongue plate engages when it is inserted into the buckle device to a predetermined depth, and which is urged at all times in the direction of engagement with the tongue plate, an ejector for urging said tongue plate in the direction of withdrawal from said buckle device, and a preventing member for preventing the lock member from moving into the insertion path of the tongue plate until the tongue plate reaches the predetermined engagement position.
With such an arrangement, the tongue plate undergoes no frictional force deriving from the lock member, and unless the tongue plate is inserted to the predetermined depth where it can firmly engage with the lock member, the ejector drives the tongue plate back out of the buckle device, thereby assuring reliable engagement between the tongue plate and the lock member.
