DESCRIPTION OF PREFERRED EMBODIMENTS

(10) The fastening clip according to a first embodiment of the present invention is shown in a perspective view in FIG. 1. This fastening clip comprises a clip body 1 comprising a pair of side walls 2, each side wall 2 being provided with one window 3. The clip body 1 is preferably made from a metal.

(11) The fastening clip also comprises a pair of retaining portions 4, a part of which protrude through said windows 3 in the rest and use positions, as shown in FIGS. 1 and 2.

(12) These retaining portions 4 are preferably made in one piece with the clip body 1 and they are elastic, which means that they are deflected during the placement of the fastening clip in its use position, returning to the shown position when the fastening clip is mounted in its position.

(13) Each of said retaining portions 4 are joined to the side walls 2 by one of their ends, and each of the retaining portions 4 comprises an end portion 5, which is the other end, i.e. the end not joined to the side wall 2. The configuration of the side walls 2 can be clearly seen in FIG. 3.

(14) The fastening clip also comprises a head portion 6 provided at an end of the clip body 1 and protruding from said side walls 2. This head portion 6 contacts with one side of the component to be fastened by the clip, as shown in FIG. 7.

(15) For preventing the jamming of the retaining portions 4 during the placement of the fastening clip in its use position, said end portions 5 comprise a bent portion 7 which is preferably a U-shape bent portion.

(16) As shown in FIG. 3, the U-shaped bent portion 7 is vertically oriented in the use position, and as shown in more detail in FIG. 4, each end portion 5 is divided in two side portions 8 by a groove 9, said bent portion 7 being in one of said two side portions 8.

(17) For permitting to fulfill the dimension requirements and for preventing the contact between the bent portions 7 during the placement of the fastening clip in its use position, the side portion 8 provided with the bent portion 7 in one retaining portion 4 is in front of the side portion 8 not provided with the bent portion 7 of the other retaining portion 4.

(18) Furthermore, the retaining portions 4 also comprise side flaps 10.

(19) As shown in FIG. 1, the fastening clip also comprises a base body 11, which is a piece e.g. made from plastic, which is placed inside the clip body 1 during the placement of the fastening clip in its use position, as shown in FIG. 5.

(20) Said base body 11 comprises verification elements 12 that in the use position are placed in the groove 9 between said side portions 8, pressing flaps 13 that are pressed against the head portion 6 in the use position, an inserting surface 14 and abutment elements 15 that contact internally the side walls 2.

(21) The verification elements 12 fix the base body 11 to the clip body 1 and the inserting surface 14 is used as a surface to be pressed by an operator for placing the fastening clip in its use position.

(22) In FIG. 5 a second embodiment of the fastening clip is shown. For simplicity reasons, the same numeral references are used.

(23) The differences with respect to the previous embodiment are the following.

(24) Firstly, the clip body 1 comprises a hook 17 extending from one of the retaining portions 4 for preventing the accidental aperture of the fastening clip.

(25) Secondly, the clip body 1 comprises a stopper 18 for preventing the deformation of the clip body 1.

(26) Thirdly, the clip body 1 also comprises a mounting flap 19 placed between the side wall 2 and the head portion 6.

(27) In FIG. 6 a third embodiment of the fastening clip is shown. For simplicity reasons, the same numeral references are used.

(28) The main difference in this embodiment is that the bent portions 7 provided at the end portions 5 also comprise an appendix 16 at the distal end of said bent portions 7, said appendix 16 being directed inwardly.

(29) Furthermore, the side walls 2 are completely vertical and define a substantially circular bent portion with the retaining portions 4.

(30) In FIG. 7 a fourth embodiment of the fastening clip is shown. For simplicity reasons, the same numeral references are used.

(31) The main difference in this embodiment is that the side walls 2 are also completely vertical, but they do not define a substantially circular bent portion with the retaining portions 4, but a curved bent portion for reducing the height of the fastening clip with respect to the fastening clip according to the third embodiment.

(32) It is clear that the features of the described embodiments can be combined as desired.

(33) The process for placing the fastening clip in the use position is shown in FIGS. 8-10.

(34) Before providing the fastening clip to the operator, the base body 11 is inserted inside the clip body 1 (FIG. 8) fixing the base body 11 to the clip body 1.

(35) When the fastening clip is mounted, the fastening clip is inserted in a hole for fixing one component to another, e.g. for fixing an airbag to a mounting surface of a vehicle. During the insertion, the retaining portions 4 are deflected inwardly when the retaining portions 4 contact the side edges of this hole. To this target, the retaining portions 4 have an inclined or sloped configuration.

(36) When the retaining portions 4 pass the hole, they return to its original position thanks to their elastic nature. Due to the verification elements 12 are inside the hole, they follow the movement if the verification elements 12 have been opened correctly.

(37) Finally, as shown in FIG. 10, the components are fastened together by the retaining portions 4 and the head portion 6.

(38) Even though reference has been made to a specific embodiment of the invention, it is obvious for a person skilled in the art that the fastening clip described herein is susceptible to numerous variations and modifications, and that all of the details mentioned can be substituted for other technically equivalent ones without departing from the scope of protection defined by the attached claims.
