Abstract

An assembly of a first element with a second element includes an elongate thin lip belonging to the second element being inserted in an elongate narrow slot formed by three sides of an elongate flat plate fixed in parallel to a flat wall of the first element. At least one element forming a guide is secured to a long side of the elongate flat plate forming an edge of the slot. The element forming a guide includes a sliding surface extending in the continuation of the elongate flat plate and diverging from the flat wall away from the first element. The at least one element forming a guide cooperates with the lip so that the insertion of the lip into the slot begins with the sliding of the lip on the sliding surface and then continues as the lip advances, with progressive insertion of the lip into the slot.

First claim

1 - 10 . (canceled)

11 . An assembly, comprising:
a first element assembled with a second element, including an elongate thin lip belonging to the second element being inserted in an elongate narrow slot formed by three sides of an elongate flat plate fixed in parallel to a flat wall of the first element, wherein at least one element forming a guide is secured to along side of said elongate flat plate forming an edge of the slot, wherein said element forming a guide comprising a sliding surface extending in the continuation of said elongate flat plate and diverging from the flat wall away from the first element, wherein said a east one element forming a guide cooperates with the lip so that the insertion of the lip into the slot begins with the sliding of the lip on the sliding surface and then continues as the lip advances, with progressive insertion of the lip into the slot,

12 . The assembly as claimed in claim 11 , wherein the sliding surface of the element forming a guide is a flat surface forming a plane which is inclined relative to said elongate flat plate.

13 . The assembly as claimed in claim 12 , wherein the sliding surface comprises laterally two areas of greater inclination than an inclination of said sliding surface.

14 . The assembly as claimed in claim 11 , wherein the sliding surface of the element forming a guide is a surface having a curved cross section.

15 . The assembly as claimed in claim 11 , further comprising a single element forming a guide extending over substantially an entire length of said slot.

16 . The assembly as claimed in claim 11 , further comprising at least two separate elements forming a guide arranged along the slot.

17 . The assembly as claimed in claim 11 , wherein, on a face opposing the slot, said flat wall has at least one stop extending in an extension of a long edge of the slot substantially perpendicular to said flat wall, said stop being arranged so as to block the lip and to prevent the lip from passing outside the slot.

18 . The assembly as claimed in claim 11 , wherein the first element comprises inside the slot a plurality of wedging ribs arranged perpendicular to the direction of insertion of the lip into the slot and perpendicular to the flat wall and to the flat plate, said wedging ribs being arranged so as to cooperate with the lip when the lip is inserted into the slot so as to guide the lip to the back thereof and to wedge the lip perpendicular to the flat wall when said lip is fully inserted into the slot.

19 . The assembly as claimed in claim 11 , wherein the elongate thin lip has a concave edge in the direction of the first element and is terminated laterally by protruding points.

20 . The assembly as claimed in claim 11 , wherein the first element is a fan nozzle and the second element is an air guide in a motor vehicle.
