Abstract: An apparatus for use in a fluid medium which activates at a deeper depth and then releases at a lesser depth. A rod depresses a spring in a housing. The rod is prevented from being ejected from the housing by a ball bearing which engages between openings in the rod and the housing. When in use, the pressure exerted by the fluid medium forces the rod deeper into the housing. When the first depth is reached the ball bearing disengages from the rod and the device is activated. As the activated apparatus rises, the pressure on the rod decreases and the rod moves out of the housing. When the deployment depth is attained the housing floods and the rod is ejected.

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.

Abstract: A first part of plastic material (7), preferably a component of a package, is secured to a second part (2). Tubular projections (9) are formed in the first part and are introduced through a hole (4) in the second part. The projection (9) is shaped with an outer terminating portion (11, 12) closing the same, and forming a vaulted termination extending outwardly and provided with such a crease that it can be brought to an at least somewhat inwardly bulging position. After the second part (2) with its hole (4) has been placed on the projection (9), a surface is laid against the vaulted termination and is pressed against the same, so that it is inversely forced into its inwardly bulging position. In this position it causes such a widening of the portion (10;14) of the projection located inside of the termination that this portion forms a rivet head (13;19).
