Abstract: A buckle that can be manufactured at lower cost and is not unlocked even when a tongue plate is pushed in a locked state is obtained. An intermediate arm 60 is fixed to a lock spring 54 attached to a button 28. Facing walls 68 of leg portions 66 of the intermediate arm 60 face distal ends of horn pieces 26 of an ejector 22. In the locked state, a predetermined clearance 72 is formed between the facing walls 68 and protrusions 70 of the horn pieces 26. Accordingly, even if a tongue plate 20 is moved further in the direction of the arrow A, the facing walls 68 are not moved in the direction of the arrow A. The button 28 is not moved in an unlocking direction (the direction of the arrow A), either, and movement of a latch 48 in a disengaging direction (the direction opposite to the arrow B) is certainly prevented. As protrusions 38 can be formed in a small size, a buckle 10 is formed in a small size, and the buckle 10 can be manufactured at lower cost.

Abstract: A buckle for vehicle safety belt systems equipped with a belt pretensioner engaging on the buckle is provided. The buckle has a release button with a cutout wherein a pushbutton is slidably received. The release button carries a two-armed blocking lever pivotally mounted thereon. In normal use, the blocking lever, when the pushbutton is depressed, is pivoted away from a stop member on the buckle housing to permit the release button to be moved until the buckle opens. When after activation of the belt pretensioner the buckle has reached the end of its stroke the release button tends to continue its movement, but the two-armed lever will hit on the stop member to prevent the release button from moving towards its release position.

Abstract: A cover which fits over a restrain harness buckle assembly. The cover slides down over the buckle and confines the ends of cam support pins in the assembly, eliminating the need for the use of pins with heads on one end, for fasteners to hold such pins in place, and the need for machining threads or grooves on the pins to cooperate with such fasteners. Additionally, the cover provides a smooth, contoured appearance which insures that nothing protrudes from the buckle assembly which might snag clothing or scratch skin. Thus, the cover eliminates the need for extra parts, machining, and assembly while providing a neater appearance.

Abstract: A seat belt buckle has a latching member (7), which engages the tongue of the buckle. The latching member is pivotally mounted on a channel member, engaging lugs (18) formed in apertures in the side walls of the channel in a substantially friction-free manner. The lugs are deformable so that, in an accident situation, the lugs deform and the periphery (17) of the latching member (7) engages the periphery of each aperture in each side wall of the channel. Thus the latching member has a substantially friction-free movement, buth the latching member is able to withstand severe forces.

Abstract: A buckle apparatus for use in a seatbelt system for a vehicle designed to protect an occupant in an emergency situation of the vehicle includes a buckle body into which a tongue plate is inserted. A lock plate is moved in a direction orthogonal to the tongue plate inserting direction and is engaged with an opening formed in the tongue plate, and portions of the lock plate on both sides of its portion engaged with the tongue plate are supported by the buckle body, thereby reliably obtaining a sufficiently large tongue plate holding strength. When the force applied to the tongue plate such as to pull it out from the buckle apparatus is relatively small, a resilient member retains the lock plate, together with the tongue plate, in such a manner that they are separated from the engaging portions of the buckle body.

Abstract: A jewelry clasp in which a blade member is captured in a case member by a latch normally located in a latched position to secure the blade member in the case member, the latch being displaceable along a first direction in response to movement of the blade member into the case member for latching purposes and displaceable along a second direction transverse to the first direction, in response to a selectively moved actuator, for unlatching purposes, to selectively release the blade member from the case member, a first spring biases the latch along the first direction and a second spring biases the latch along the second direction for maintaining the latch in the latched position, and a safety lock is movable selectively from an unlocked position into a locked position for precluding inadvertent unlatching, while permitting latching independent of the position of the safety lock.

Abstract: A buckle apparatus for use in a seatbelt system is arranged such that when the tongue plate of the seatbelt is inserted into the buckle body, the pawl of a lock plate is inserted into an opening formed in the tongue plate. Since the projecting end of the pawl is separated from the corresponding opening formed in the buckle body, a relatively small force can release the tongue plate from the buckle apparatus. However, when the force applied to the tongue plate for pulling it out from the buckle apparatus increases, a lock plate holder is deformed by virtue of this force. In consequence, the pawl engages with the opening of the buckle body, and retaining wings provided on the side of the lock plate remote from the pawl also engage with the corresponding portions of the buckle body. Accordingly, the lock plate is supported by the buckle body at two portions on both sides of the portion thereof which engages with the tongue plate, so that the lock plate can bear a large tongue plate pulling out force.

Abstract: A safety belt buckle fitted with belt straps and two interlocking parts. These are designed for releasably connecting the belt strap. One interlocking part consists of a locked part and the other interlocking part consists of a locking part. The latter is fitted with a locking member pivoted in the locking part and able to be reset between the position releasing and the position locking the locked part. The locking member is spring loaded so as to attempt to pivot to its releasing position. A detent member is able to be reset between a detent position in which the locking member is prevented from being reset from its locking position and a releasing position in which the locking member is permitted to pivot to its releasing position. An ejector is arranged so as to eject the locked part by the action of a spring when the locking member is rest to the locking position. A link connects the detent member to the ejector. The link is loaded by a spring which attempts to move the ejector to its outer position.
