A thread-forming screw includes a head and a shank, the shank having a thread and a thread-forming zone at the end opposite to the head, the thread-forming zone also having a thread portion. The shank at the end opposite to the head has a spherical portion with a maximum diameter in a plane perpendicular to the axis of the shank which corresponds approximately to the mean diameter of the thread of the shank.

A neck rest includes first and second supports having first and second positions where the supports are at approximately the same level and the second support is elevated relative to the first support, respectively. A first spring is supported by the first support and rotatably connected to the second support to bias the second support into the second position. A movable locking element biased by a second spring on the first support automatically blocks the second support in the second position. A locking element is movably supported by the first support and cooperates with a projection of the second support to lock the second support in the first position. A releasing element is movably supported by the first support and releases the locking element when actuated. A supporting member is located between the supports in the second position for transferring shock forces from the second support to the first support.

A molded plastic rivet for affixing two parts to each other when the rivet is inserted through two mutually aligned apertures in the parts. The rivet includes a pin having a pin head, a pin shank and first and second pin latching offsets at the distal end of the pin shank. The latching elements include at least first latching offsets. The rivet also includes a rivet body having a rivet body head, and a rivet body shank that is insertable in the apertures and comprises several legs running away from the head of the rivet body, these legs being joined to each other distally into a nose tapering toward the longitudinal axis of the rivet body, a passage being formed between the legs and passing through the head of the rivet body, each leg being fitted at a distal end thereof with a first locking surface element facing the passage for engaging the first latching offsets of the pin once the pin has been driven completely into the rivet body, where, in a pre-assembled state, the pin shank is partly insertable into said passage, the legs running radially outward to the rivet body's longitudinal axis, each leg being fitted at a proximal end thereof with a second locking surface element engageable with the first latching offsets of the pin in the pre-assembled state, wherein approximately diametrically opposite protrusions are configured on the side of the head of the rivet body at regions opposite the shank of the rivet body and are fitted with recesses or apertures for receiving respective arms of a fork-shaped assembly tool.

The disclosure concerns a clip having a first shank including a distal end and a proximal end, a head attached to the distal end, a resilient flange attached to the first shank proximate to the proximal end, a second shank extending downwardly from the resilient flange, wherein the second shank includes a free end. A pair of spring members extending obliquely from the free end to the resilient flange, each of the pair of spring members being attached to the resilient flange by a snap-in shoulder, and a pair of longitudinal members extending from the free end and each having a securing element at an opposing end proximate to the resilient flange, wherein the pair of longitudinal members and the securing elements are movable inwardly and outwardly as a result of the pair of spring members flexing inwardly and outwardly, respectively.
摘要:
A plug to hermetically seal an aperture in a sheetmetal, or in the floor of a vehicle, comprising, a cap covering the aperture and comprising an external, circumferential flange resting on one side of the sheetmetal or of the floor and fitted with a first circumferential seal, an affixation portion entering said aperture and, a second circumferential seal configured at the cap or at the affixation portion and being a distance from the first seal and resting against the sheetmetal or the said floor, a cavity being subtended by the sheetmetal or said floor, the two seals and at least one wall of the plug, where said plug, includes a pressure-compensating chamber, which communicates with the cavity and, which compensates a change in pressure, caused by a change in temperature, inside the cavity, by changing the volume of the pressure-compensating chamber.
