Abstract: An adjustable positioning element (1) enabling a component (7) to be positioned and fastened in three dimensions is provided. The element comprises a bolt (2) with which the component (7) can be positioned in an axial direction (z) of the bolt (2), a hollow body (4) presenting an annular end wall through which the bolt passes, and a fastener element (5) with a washer (25) surrounding the bolt and arranged to be movable sideways against the end wall of the hollow body (4). The washer (25) is designed to be pressed against the end wall of the hollow body when the fastener element is attached to the bolt so as to fix the lateral (xy) position of the bolt (2) in the hollow body (4). The fastener element (5) and the bolt (2) are arranged to attach to each other by reversible snap-fastening.

Abstract: A self-drilling rivet (1) is provided. The self-drilling rivet comprises a bearing collar (3) and an expandable hollow tubular body (2), the body (2) having, at one end, a first cylindrical portion (5) adjacent to the collar (3), and at the other end of the body (2), a second cylindrical portion (6) arranged to receive a drill element (4), and between the cylindrical first and second portions (5, 6), a third portion (7) that is expandable. The third portion (7) of the body (2) and the drill element (4) have respective connection means (11, 15) that are arranged so as to separate the drill element (4) from the body (2) during expansion of the third portion (7) of the body (2).

Abstract: A self-piercing rivet comprising a bearing flange and a piercing end with an expandable hollow tubular body extending axially between the flange and the piercing end, the body comprising a cylindrical first portion that is adjacent to the flange, a cylindrical second portion that is adjacent to the piercing end, and a radially-expandable third portion between said cylindrical first and second portions, the rivet further comprises a breakable rod that extends axially inside the hollow body to drive the body in axial rotation and to deform it radially at said expandable third portion under the effect of axial traction. The third portion (7) of the body is designed to produce, before being deformed radially, an abrasion or deburring effect on the peripheral edge of a hole being pierced by the piercing end.

Abstract: A self-piercing rivet comprises a bearing flange and a piercing end with a radially-expandable hollow tubular body extending axially between the flange and the piercing end, the body comprising a cylindrical first portion that is adjacent to said flange, a cylindrical second portion that is adjacent to said piercing end, and an expandable barrel-shaped third portion between the cylindrical first and second portions, and a bushing arranged in the second portion that is designed to be driven in axial translation towards the flange. The bushing extends axially inside the third portion of the tubular body in such a manner that it is inserted into said first portion of the body when the third portion is completely expanded. The third portion of the body is designed to produce, before being deformed radially, an abrasion or deburring effect on the peripheral edge of a hole being pierced by said piercing end.

Abstract: A fastener is provided with a snap-fitting leg to be pushed through an opening of a panel, the snap-fitting leg including a flat rigid core which extends in an axial direction and at least one curved flexible flange having an inner longitudinal edge running alongside the core which is separated from a free outer longitudinal edge of the flange by a web with a concave inner surface. A stiffening rib is provided on the concave surface of the web of the flange. The rib connects to the free outer longitudinal edge of the flange at two remote points substantially aligned in the axial direction.

Abstract: The invention relates to a fastener (1) provided with a snap-fitting leg (2) to be pushed through an opening of a panel, said snap-fitting leg (2) including a flat rigid core (8) which extends in an axial direction (A) and at least one curved flexible flange (9) having an inner longitudinal edge (10) running alongside the core (8) which is separated from a free outer longitudinal edge (11) of the flange (9) by a web (12) with a concave inner surface. A stiffening rib (14) is provided on the concave surface of the web of the flange (9). Said rib connects to the free outer longitudinal edge of the flange at two remote points substantially aligned in said axial direction (A).

Abstract: A device for covering a recess (4) formed in a covering strip (5) has a flap (3), which is rotatable about a longitudinal axis, and a bearing arrangement for holding the flap (3) in bearing regions on the end side. There are journals (15, 16) with resilient fork limbs (18, 19) on the end side, wherein at least one fork limb (18, 19) is designed with a latching lug (20) on the end side. Furthermore, bearing sleeves (7, 8) are formed which each have a journal-receiving space (9) which extends in the direction of the longitudinal axis of the flap (3) and into which a journal (15, 16) can be fitted until it engages behind an edge side of the bearing sleeve (7, 8) by way of a latching lug (20).

Abstract: A device for fastening an add-on part, which is formed with tongue-like projections, to a support part has members (1, 2) which are connected to one another. At least a number of the members (1, 2) has a cage wall (3) which surrounds a receiving space (14) and on which is formed a ramp structure (13) which projects into the receiving space (14) and has an inclined piece, which rises obliquely from an inlet side to an outlet side of the respective member (1, 2), and a stop piece. The stop piece has a greater spacing from a contact side of the cage wall (3) than that region of the inclined piece which is adjacent to the inlet side. In this way, when the ramp structure (13) is in engagement with pins which are attached to the support part, the members (1, 2) press against the tongue-like projections and fasten the add-on part to the support part.

As a result, the device can be handled in a simple manner as a unit with relatively little outlay on material.
