Embodiment Construction

[0028] figure 1 Shown is an aluminum side door frame 10 comprising a frame reinforcement 11 defining a window opening, a waistline reinforcement 12 defining a molding area below the window opening, an angled intrusion reinforcement 13, A reinforcement 14 of the rear part of the housing and a reinforcement 15 of the front part of the housing, all of which are made of aluminum or any other strong but relatively lightweight material. The aluminum frame 10 is designed to receive an outer skin 20 of the side door on the outside of the vehicle and an inner lining of the side door 30 on the inside ( image 3 ).

[0029] The outer skin 20 is divided into several parts: an upper part following the upper part of the door frame 11 around the window opening, and a lower part forming an outer panel covering the bottom of the door below the window opening, in image 3 and Figure 4 This lower portion is shown secured to the waistline reinforcement 12 in .

[0030] The inner liner 30 is p...

Abstract

The invention relates to an inner structural finish for a vehicle side door, and side door thus equipped that includes a filled molded resin inner finish (30) in the form of a first sheet that includes a substantially vertical main portion (30a) which is connected to an oblique top portion (30b) which is turned over at a recess and made of a composite molded plastic that is made structural by a strip reinforcement (40) in the form of a second sheet comprising three planar portions (41, 42, 43) that form longitudinal edges (44) therebetween and are rigidly connected to the first sheet so as to form, with said sheet, a hollow body (60) that provides resistance to longitudinal compression forces.

Description

technical field [0001] The present invention relates to a side door of a motor vehicle and an inner lining portion thereof. Background technique [0002] In a conventional design, for example in the document WO 2010 / 125264 signed by the applicant image 3 As shown in , the side door consists of a sheet metal structure (steel and aluminium) and is realized on the one hand on the outside of the vehicle by an outer skin and by one or more inner lining parts made of plastic Realized on the inside. In particular, the upper region of the front side door is constituted by a structural part made of sheet metal followed by a door inner lining made of (plastic) composite material in one or more parts. The sheet metal structure consists of a door shell, a steel door molding and the assembly (spot welding and / or riveting and / or gluing) of the molding to the shell. [0003] This assembly is structural in order to resist crashes: both frontal and side impacts. Characteristically, the d...
