[0003] A disadvantage of currently known spring nuts is that they can only be used with one specific bolt size
Also, the length of the bolt needs to be precisely adapted to the part to be attached or the spring nut, preventing the bolt from protruding on the rear side of the spring nut, which is not ideal

Embodiment Construction

[0018] figure 1 A spring nut 10 for attachment to a bolt 12 is shown. The spring nut 10 can be used to attach a first component 14, such as an upholstery component, to a second component 16, such as a vehicle body (see figure 2 ). The bolt 12 is in this case firmly fitted to the second part 16 , for example welded thereto. The first part 14 has an opening 18 through which it fits over the bolt 12, after which the spring nut 10 is slid onto the bolt 12 and secured thereto. Thus, the first part 14 is pressed against the second part 16 by the spring nut 10 and held fixedly thereon.

[0019] From figure 1 and figure 2 As can be seen in FIG. 2 , the spring nut 10 has an annular contact area by which the spring nut 10 rests against the first component 14 and on which an insertion opening 30 for the bolt 12 is provided. The contact area 20 transitions into a substantially cylindrical outer wall 22 of substantially cylindrical design, the front surface of which is designed to ...

Abstract

The invention relates a spring nut (10) attached on a bolt (12). The spring nut is provided with a roughly oval seat used for the bolt (12). The seat is provided with an axial inserting opening (32) used for the bolt (12) and a maintaining portion used for the bolt (12). The spring nut (10) completely surrounds the seat along a circumferential direction on a front wall (28) opposite to the inserting opening (32).

Description

technical field [0001] The invention relates to a spring nut for attachment to a bolt, the spring nut comprising a substantially oval seat for the bolt, the seat having an axial insertion opening for the bolt and a retaining portion for the bolt . Background technique [0002] This type of spring nut is used to fasten a component, such as an interior liner component, to a second component, such as a vehicle body component. To this end, the body parts are provided with bolts to allow the spring nuts to slide over them and to be fixed thereto. The part to be attached has an opening through which it first slides over the bolt, then the spring nut slides over the bolt and presses against the second part so that the second part is held in place on the bolt. Such a spring nut is disclosed, for example, in DE 197 33 771 C1. [0003] A disadvantage of currently known spring nuts is that they can only be used with one specific bolt size. Also, the length of the bolt needs to be p...
