  • the object of the invention is therefore to attach a plastic fender to the vehicle body in such a way that bulging is prevented at all edge regions of the fender due to thermal expansion.
  • the plastic fender Since the plastic fender is screwed according to the invention only to the corner area lying between the first and the second edge area, it can in the case of thermal expansion - regardless of whether it is due to the weather or when painting the vehicle - move both along the hood-side and along the support column-side edge area, so that the plastic fender cannot bulge or deform in a similar way.

  • Both the elongated holes and the guide elements are very inexpensive to provide, the guide elements consisting of metal or plastic being light in weight (features of claims 1, 2 and 5).
  • the plastic fender is received near the fixed point formed by a screw by a vehicle-mounted screw with a receptacle, which is surrounded by a through hole provided on the first edge area with radial play. This ensures that the plastic fender can shift slightly with respect to the fixed point, the receiving bushing or instead of this a correspondingly designed screw head for a joint or similar installations located in this area is not a hindrance (features of patent claim 3 ).
  • the elongated holes have a somewhat greater longitudinal extension towards the area of the free ends of the fender, that is, with the length of the fastening section of a guide element of, for example, 20 mm, the length of an elongated hole near the through hole is, for example, 30 mm, while the elongated holes located near the free end of the fender are approximately 45 mm long.
  • the plastic fender can stretch out unhindered in the event of thermal expansion, but for reasons of strength, for the elongated holes located near the through hole or the fixed point, such a hole Longitudinal extension such as the elongated holes located at the free end of the fender is dispensed with (features of claims 4 and 5).
  • the guide elements For the detachable fastening of the guide elements to the vehicle body, they have a fastening section which is rectangular in plan view, the width of which is smaller than the width of the elongated hole, so that the plastic fender can move longitudinally without hindrance, regardless of thermal expansion, manufacturing and assembly tolerances.
  • the fastening section can be fastened to the vehicle body in a simple manner by means of a continuous screw or — in the case of production from plastic — by means of an integral screw shaft (features of claims 6 and 10).

Abstract

L'invention concerne une aile (10) de voiture en matière plastique, comprenant un premier bord (1), supérieur, et un deuxième bord (2), presque perpendiculaire au premier. L'aile (10) est fixée à la carrosserie (3) du véhicule par le deuxième bord (2), au moyen d'une vis (4). Le premier et le deuxième bord (1 et 2) comportent en outre plusieurs trous oblongs (11) espacés, dans lesquels se trouve respectivement une partie de fixation d'un élément de guidage (13), lequel est monté sur la carrosserie (3) du véhicule au moyen d'une vis de fixation (15). Sur chaque partie de fixation des éléments de guidage (13) est disposé un bord de guidage recouvrant les bords longitudinaux d'un trou oblong (11) opposé, de sorte que, lors de la dilatation thermique, l'aile (10) peut s'allonger sans rencontrer d'obstacle à partir de la zone d'un point fixe (b) dans le sens des flèches (d et e), l'étirement en longueur de la partie de fixation (12) des éléments de guidage (13) étant inférieur à celui du trou oblong (11).
