Abstract: A device for enabling a first part to be detachably assembled to a second part, the device comprising a first fastener and a second fastener fixed respectively to the first part and to the second part, assembly being obtained by engaging the fasteners along an "Engagement" axis, with engagement causing a retaining component of the first fastener to be inserted by deformation into a reception component of the second fastener, wherein:the first fastener is fitted with return means tending to move it away from the second fastener;the second fastener includes resilient means exerting pressure on the retaining component when inserted in the reception component to keep it therein, said resilient means being fitted with a return device to move them away from the retaining component during detachment; andthe retaining component and the reception component are complementary in shape.

Abstract: A lock pin mechanism for a negative "G" pilot's harness includes a contoured strap lug received within a metal keeper. A lock pin passes through the keeper and engages the lug. A bearing surface exists between the lug and the keeper so that high upward forces exerted on a negative "G" strap are transmitted to the strap lug but become shared between a lug-pin interface as well as a lug-keeper interface. Thus, binding frictional engagement between pin and lug is avoided so that safe and secure withdrawal of the pin is achieved when required.

Abstract: A coupling for attaching a seat back to a seat cushion particularly for an automotive seat assembly in which the coupling includes a tapered plate member extending upwardly from the rear of the seat cushion and a housing attached to the frame of the seat back into which the plate member is inserted by moving the seat back down onto the seat cushion. A spring biased wedge is disposed within the housing and biases the plate member toward one side of the housing. When the plate member is fully inserted into the housing, one sidewall of the housing is seated into a recess in the edge of the plate member and held in place by the wedge. Once the sidewall housing is seated in the plate member recess, movement of the housing relative to the plate member is prevented. The seat back is removable for servicing by moving the wedge out of its position holding the plate member in place so as to enable the housing sidewall to be withdrawn from the plate member recess to enable separation of the housing and plate member.

Abstract: A plug-type clasp for pieces of jewerly, in particular for necklaces, composed of a housing in which a sleeve is movable under the force of a spring. The sleeve has a receiving opening into which a connecting element can be inserted through a front-end opening of the housing and locked there. Both the front-end opening of the housing and the receiving opening of the sleeve are eccentrically offset from each other, so that the connecting element can only be inserted into the housing, and locked there, only after the sleeve has been pulled back against the force of the spring. Removal of the connecting part can take place in the correspondingly reversed order. Activation of the sleeve for unlocking the plug-type clasp takes place by means of an operating button, laterally guided in a longitudinal hole of the housing, so that the actual connecting areas of the plug-type clasp for pieces of jewelry, in particular necklaces, remain free of pulling stresses during the operation of the plug-type clasp.

Abstract: This buckle, which is particularly for automobile safety belts and is intended to fix in a movable manner a side thereof to a fixed point in the body of the vehicle, comprising a hook assembly and a bolt (19) which is connected to the side to be fixed, with the hook assembly comprising, housed in a housing (1), a body (4) intended to be fixed to a holding means which is connected to the vehicle and which defines a passage and a sliding plane for said bolt, means for locking the bolt in the buckle, means for releasing the bolt and means for ejection thereof, is characterized in that the locking means are composed of a part (17) projecting from the body (4) extending into said passage, intended to be engaged into a cavity (20) of the bolt (19), in the locked position, and in that holding means (7) are provided for holding the bolt (19) in the locked position on said projecting part (17) of body (4).

Abstract: A releasable connector having a male member with spaced prong ends and a tubular female member having an open end for receiving said prong ends and divided at said open end into legs by axially extending slots and a unitary locking means removably interposable between the prong ends and an annular portion for bridging the joint interface between the interlocked male and female members.

Abstract: A release arrangement for a sailboard footstrap (10) which has a female member (22) and a male member (74). The female member (22) is composed of two identical components (38,40) which locate together by means of pins (52,152) locating in apertures (154,54). Chamfered apertures (48,148) in resilient arm portions (46,146) of the female member (22) are adapted to receive and retain frusto-conical bosses (94,90) on the male member (74). The bosses (94,90) are located on a portion (82) of the male member (74), the sides (84,86) of which abut pins (52,152) when relative rotation of the members (22,74) about the engaged bosses and apertures (94,48; 90,148) occurs, the abutment serving to lever the bosses (94,90) from the apertures (48,148) at a predetermined magnitude of force exerted to cause rotation. The male (74) and female (22) members may also disengage at other predetermined magnitudes of forces exerted upon the arrangement in other directions.

Abstract: A mechanism for coupling a strut (30) to a nodal element (32) comprises a female coupling fixture (31) and a male coupling fixture (33). The female coupling fixture (31) includes an elongate cylindrical member (35), a distal end of which is hemicylindrically configured with an inner surface that is contoured to receive a conjugately contoured knob on a distal end of the male coupling fixture (33) in mating engagement. The female coupling fixture (31) also includes a sleeve (36), which is slidable coaxially from an OPEN position around an intermediate portion of the cylindrical member (35) to a LOCKED position around the matingly engaged distal ends of the cylindrical member (35) and the male coupling fixture (33). Spring-biases locking bars (50) and (51) maintain the sleeve (36) in the LOCKED position.

Abstract: A quick disconnect mechanical coupler includes a housing having a longitudinal slot within which is positioned an elongated coupling pin which is displaceable within the slot along the length thereof. A first end of the housing is adapter to receive a mounting lug coupled to a first structure while a lateral portion of the housing is adapted for coupling to a second structure. With the mounting lug positioned in the first end portion of the housing, the elongated pin, which includes a knob at one end, is spring-biased in a firt direction for insertion in an aperture in the mounting lug to securely couple the housing thereto. Displacement of the coupling pin in a second, opposite direction disengages the housing from the lug and disconnects the first and second structures. The pin is provided with first and second locking projections positioned along the length thereof and extending transversely therefrom.

Abstract: In a buckle device in which a tongue plate is inserted into a buckle body secured to a vehicle body and is latched to a lock lever disposed in the buckle body, an opening portion of the tongue plate and a pawl of the lock lever are caused to contact with each other at two points spaced in a predetermined distance and a clearance is formed between the opening portion and the pawl in respect of the two points.In an ordinary situation of the vehicle the clearance is kept smooth, and, when a large load acts upon the tongue plate in an emergency situation of the vehicle, the contact portions of the opening portion and the pawl at the two points are deformed, whereby portions of the opening portions and the pawl existing between both the points are caused to contact with each other.Accordingly, the lock lever is capable of being operated with a small force and the tongue plate can be pulled out of the buckle device smoothly.
