A coupling seat provides a seat space in which the coupling head of a coupling bolt can be releasably locked and moved linearly in the seat space. The seat has a wall that surrounds the seat space, and the dome has a locking structure to fasten the coupling seat in an installation opening in a component. The seat has an open end and a closed end with a locking structure for the head of the coupling bolt. The locking structure of the dome comprises latching bars that are arranged opposite each other on an inner wall of the seat space and parallel to a longitudinal axis of an inner dome cross-section and form an undercut opposite the insertion direction. The locking structure permits movement of a coupling bolt along the latching bars in the seat space transverse to the insertion direction.

A fastening assembly includes a receiving seat and a clip having an operation portion, a holding portion, an insertion portion, and a pair of connection leg portions. The receiving seat includes a neck portion and a receiving channel. The insertion portion connects to the operation portion by the pair of connection leg portions, and the holding portion connects to the operation portion. When the clip is mounted on the neck portion of the receiving seat, the insertion portion of the clip is at least partially inserted into the receiving channel through the opening in a first neck portion side wall, and the holding portion of the clip abuts against a second neck portion side wall. When a pushing force is applied to the operation portion toward the neck portion, the insertion portion can be withdrawn from the receiving channel, such that the clip can be removed from the receiving seat.

A fastener having two branches extending on either side of a median plane, each branch carrying a tongue, the tongues defining between them a throat between the two branches. When the fastener is reversed with respect to another identical fastener, their respective median planes forming a non-zero angle between them, one branch of the fastener having its distal portion in contact with at least one of the two tongues of the other fastener and its outer face in contact with an inner face of one branch of the other fastener, the distal portion of the other branch of the fastener is substantially in contact with the distal portion of the other branch of the other fastener.

A grommet (200, 300, 400), a stud (102), an assembly of a grommet and a stud forming a fastener (100), and a method of assembling a grommet and a stud to form a fastener has the grommet with an interengaging element (250) in a channel wall of the grommet for engaging a cooperating, compatible or complementary interengaging element in a wall of the stud. The grommet and the stud can be assembled by moving the grommet and the stud relative to each other until the interengaging element in the grommet engages the complementary interengaging element in the stud. A family of grommets is described.

A u-shaped metal portion and a u-shaped plastic portion can be coupled together to define an interior rib receiving cavity between both the metal sides and the plastic sides. The u-shaped metal portion can include a first metal rib retention barb extending interiorly of the plastic portion in the interior rib receiving cavity and can be designed to engage the rib to couple the dual material U-base fastener to a first component rib with the rib received within the interior rib receiving cavity. The u-shaped plastic portion can include a first plastic aperture retention wing extending exteriorly of the metal portion and designed to engage a second component aperture to couple the dual material U-base fastener to the aperture with the inner plastic and outer metal insertion ends extending through the aperture.

A coupling bolt includes a connecting portion with which the coupling bolt is fastenable to or in a first component, and a shaft extending from the connecting portion and defining a longitudinal axis of the coupling bolt. The shaft has a pre-fixation portion and a fastening portion, and along the longitudinal axis in the direction of the connecting portion the pre-fixation portion comprises a first head portion with a first diameter, a subsequent first, tapering transition portion and a first locking portion with a second diameter which is smaller than the first diameter. Along the longitudinal axis in the direction of the connecting portion, the fastening portion includes a second transition portion adjacent to the first locking portion, a subsequent second head portion with a third diameter that is larger than the first diameter, a third tapering transition portion and a second locking portion.

A U-base clip component can include a pair of rib coupling barbs which can extend inwardly from two opposing clip side walls. A seal component can include two opposing aperture retention wings coupled to a central wall. A first and a second component annular seal can extend from opposite respective sides of the central wall. The U-base clip component and the seal component can define an interior rib receiving cavity between both the clip side walls and the aperture retention wings. A pair of rib coupling barbs can extend into the interior rib receiving cavity from the clip side walls and the two opposing aperture retention wings can extend exteriorly from the clip side walls. The rib coupling barbs of the U-base clip can be designed to couple fastener to the rib and the aperture retention wings can be designed to couple the dual component sealing fastener to the aperture.

A pedal assembly comprises a pedal arm; a pedal plate provided on a second end of an elongated lever structure of the pedal arm; a vehicle mounting bracket; and a retainer. The retainer is installed on the pedal arm and is configured to operatively connect the pedal arm and an end portion of an operating member so as to transmit the movement of the pedal arm between a first and a second arm position to a functional system. The retainer is in an open position for insertion of the end portion of the operating member therein. The retainer is configured to move or to be movable from the open position to a closed position in which the retainer retains the end portion of the operating member received therein. The retainer is movable from the open position to the closed position by insertion of the operating member therein.

A fastener clip system including a carrier and a fastener clip configured to fit over the carrier. The fastener clip includes at least one wing. The wing includes an engagement region that includes a depressed portion configured to be secured against a slot.

A fastening device for attaching an assembly comprising at least two planar elements, comprises: A clip for insertion into openings in the planar elements for holding the planar elements together including a planar head having a central opening for providing access to an inner cavity of the clip; two lateral upright members having a first end that is secured to the head and a second end, the second ends being joined to each other; and a pin that is intended to be inserted into an inner cavity in the clip in order to lock the assembly. The pin comprises at least one flexible bridging piece having a central portion that is connected to a main body of the pin by means of two flexible portions, and the pin contacts a lateral upright member of the clip to lock and hold the assembled planar elements together.
