This buckle is characterized in that the resilient means for ejecting the bolt and the means pushing the locking member (5) towards its locking position consist of a spring (14) inserted between the sliding block (12) and the locking member (5).

Abstract: A cover for a control mechanism. Activation of the control with the cover in place requires more strength than a child has; thus a child cannot, as a rule, activate the control. Concurrently, activation of the control with the cover in place does not require more strength than an adult has, so an adult can activate the control. The cover may be used over a release control on a seat belt buckle. The portion of the cover overlying the control is generally deflectable, so that an adult may activate the control through the cover. Regarding deflectability of the cover, it is rigid and stiff enough that a child may not deflect it enough to activate the control, while being simultaneously sufficiently flexible and resilient that the control may be activated by an adult by deflection of the cover.

Abstract: A safety lock for a seat belt buckle includes a housing for receiving and containing the seat belt buckle therein and a locking portion for releasably retaining the housing in a closed position wherein the buckle is substantially enclosed therein. When the safety lock is assembled in the closed position on a seat belt buckle and the buckle is utilized for detachably interconnecting first and second seat belt sections, the safety lock restricts access to the buckle in a manner which normally prevents a small child from disconnecting the seat belt sections but nevertheless permits the seat belt sections to be easily disconnected by an adult.

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: By providing a pressure responsive actuator in controlled actuating engagement with a latch mechanism in which a spring-loaded indicator is securely retained, with said indicator being movable from a non-visible, retained position to a visible, released position in response to pressure exceeding a desired level, a unique, precision constructed pressure sensor and indicator is achieved. In the preferred embodiment, the latch mechanism comprises a plurality of elongated, resilient, spring-biased locking fingers, with the locking fingers being controllably disengaged from the indicator in response to the movement of the pressure responsive actuator. In addition, the present invention is also quickly and easily manually reset, thereby further enhancing the usability of the present invention.

Abstract: A molded plastic tubular sleeve slips over the housing of a seat belt buckle and includes an integrally molded flap which registers with and overlies the pushbutton of the buckle. The pushbutton flap is plastically yieldable relative to the tubular sleeve to thereby depress the buckle pushbutton underlying the flap. By controlling the material and dimensions of the tubular sleeve, the pushbutton flap can be designed to require a level of release force which is predeterminedly larger than the force normally needed to unbuckle the buckle. Furthermore, the tubular sleeve is shaped to be capable of sliding removal from the buckle so that the seat belt buckle may be conveniently restored to normal force unbuckling as desired.

Abstract: A method of making a safety belt buckle having a rigid base plate defining a belt tongue insertion path, belt tongue locking means having first component fixed to the base plate and a second component movable relative to the first component to lock an inserted belt tongue in the buckle, and an actuator element disposed on the base plate and movable relative to the base plate to cause the second component to release the tongue. The method comprises the steps of forming the first component and the actuator element as a one-piece unit which the first component and the actuator element are interconnected by the frangible connections, mounting the one-piece unit on the base plate, and thereafter moving the actuator element relative to the base plate and first component to cause the frangible connections to break.

Abstract: The child safety seatbelt securement device of the present invention includes a housing adapted for at least partially covering the release button of a female seatbelt buckle so that direct access to the release button is substantially restricted. The housing includes a mechanism for releasably securing it onto a conventional female seatbelt buckle. Finally, the housing includes an actuator mechanism which is actuatable by an adult for depressing the release button of the female seatbelt buckle on which the housing is secured. The same actuator mechanism is difficult, if not impossible, for a young child to operate, however, due to its complicated or multi-step operation or the force required for actuating it.

Abstract: A safety belt lock has a lock housing with an insertion path for an insertion tongue of a safety belt. The insertion opening of the insertion path is defined between opposed resilient flange members bearing on surface portions of the insertion tongue to generate mutually perpendicular clamping forces whereby any rattling noises are avoided.

Abstract: A buckle for safety belts, especially in motor vehicles. The buckle has a housing and a tongue which can be inserted in an opening of the latter, can be locked in the housing by at least one latching member, and is stressed by a spring-loaded ejector. To be prevented is the technical of the rattling against one another of the housing and the buckle tongue. For this purpose, at least one spring element is disposed in the housing in the vicinity of the insertion opening for the buckle tongue. At least one abutment surface of the spring element projects laterally into the path which is to be traversed by the buckle tongue upon insertion in such a way that the tongue is acted upon transverse to the direction of insertion or ejection.

Abstract: A buckle comprises a male member including a pair of resiliently flexible legs each having an abutment surface, and a female member having a socket portion releasably couplable with said legs and including a pair of spaced sidewalls defining therebetween a slot for receiving therein said legs, each of the sidewalls having a retaining surface engageable with the abutment surface to interlock the male and female members. The socket portion further has a pair of cantilevered arms disposed inwardly of the sidewalls and resiliently flexible toward and away from the sidewalls. An actuating lug is disposed on a distal end of each arm which is located outside of the slot, the lug being engageable with one of the legs. The arms are resiliently flexible toward each other to cause the actuating lugs to urge the legs to flex resiliently toward each other for bringing the abutment surface and the retaining surface out of engagement with one another.

Abstract: A seat belt buckle includes a body having a latch lever pivotally mounted thereon and including a tang struck therefrom. The latch lever has a pushbutton portion which registers with an opening in a cover attached to the body. A spring biases the latch lever to a latching position in which the tang engages into an aperture of a latch plate inserted into the buckle. A locking member, preferably of molded plastic, is slidably mounted on the underside of the buckle body and manually movable between a locking condition in which a locking abutment of the locking member blocks depression of the latch lever by the pushbutton and unlocking position enabling the pivoting of the latch lever to withdraw the tang from the aperture of the latch plate. The locking member includes an integral spring arm carrying a detent tab which engages the buckle body to retain the locking member in either its locking or unlocking positions.

Abstract: A safety belt buckle employs a pivoting latch plate for retaining a tongue plate tip within the buckle interior. A locking means for securing the latch mechanism in a latched position includes a sliding member mounted on the pivoting latch plate and urged forward by spring means.

Abstract: A one-piece plastic safety belt buckle cover employs integral structural members depending from the inside of the top portion of the cover to support it and give it strength and rigidity to resist crushing under vertical loading. The preferred structural members comprise a latticework or honeycomb of intersecting walls and ribs defining supports at the front, sides and rear of the cover. The front support is positioned above a tongue plate and spaced therefrom to engage the tongue plate when the front of the cover is deflected downward. The preferred supports include walls which extend downward inside the cover shell and are positioned to engage various surfaces of the buckle when the cover is deflected downward due to vertical loading, and include ribs which do not extend as far downward, but which also support the outer shell of the cover.

Abstract: An automobile seat belt includes a latch tongue fixed to one belt segment and having a latching aperture, and a latch housing fixed to the other belt segment, having a recess and opening at its distal end to receive the latch tongue. The tongue is automatically latched within the housing by insertion; and the tongue is released by depressing a release button through an opening in the top face of the latch housing. To render the seat belt child proof, one form of safety cover is a sleeve slipped over the latch housing, the sleeve having one end partially closed to pass the latch tongue and the sleeve having a limited access opening in one face to overlie the release button. The sleeve is retained in enclosing position on the housing by the latch tongue. The limited access opening may be a small opening only large enough to pass the tip of the ignition key to depress the release button and unfasten the belt.
