Definitions

  • the invention relates to an arrangement of an instrument panel carrier in a vehicle body according to the preamble of claim 1 and an instrument panel carrier according to the preamble of claim 4.
  • instrument panel supports run approximately rectilinearly as cross members between laterally opposite A-pillars, to which they are attached with their support ends. Such instrument panel supports are approximately at instrument panel height, i.e. H. at a distance below the parapet of the front window, so that further vehicle parts are arranged in front of the dashboard support when viewed from the front of the vehicle.
  • a relatively large-volume air conditioning heater with a stable structure is arranged in the middle area in front of the dashboard support.
  • the front end with the support structures contained therein is deformed and shortened to absorb impact energy.
  • the instrument panel support connected to the A-pillars is part of the most stable passenger compartment and should not be deformed in the event of a front impact.
  • vehicle parts in particular an air conditioning heater, which are arranged in front of the dashboard support (seen from the front of the vehicle) are displaced against the dashboard support together with a deformation of the front section in the event of a front impact.
  • the instrument panel support acts like a barrier, so that these parts, in particular heater parts, move on a block in front of the instrument panel support. This shortens deformation paths for targeted energy-absorbing deformation. The delay also increases undesirably during block formation.
  • a vehicle body with a triangular cross-section at the front end of the passenger compartment is already known (DE 197 14 631 A1).
  • This cross member forms the lower frame member of the front window, so that no vehicle parts with the above-mentioned risk of block formation in the event of a front impact can be arranged in front of such a cross member.
  • the triangular cross section of this cross member is obviously chosen here for the purpose of taking up little space and moreover has neither an explicitly mentioned nor recognizable function.
  • the object of the invention is to develop an arrangement of an instrument panel support in a vehicle body such that there are favorable deformation conditions for absorption of impact energy in the event of a front impact.
  • Another object of the invention is to propose a suitable embodiment of an instrument panel support.
  • the instrument panel support runs approximately rectilinearly in alignment in the two side areas between the A-pillars and is bent in a central area to the rear into the passenger compartment.
  • this central area expediently has an approximately straight central support part which runs parallel and offset to the rear with respect to the aligned side areas of the instrument panel support, the transitions being able to take place with relatively narrow bends.
  • the instrument panel support has a wedge profile in the central region, preferably as a triangular profile.
  • the wedge edge is directed towards the front as a transverse cutting and separating edge. This cutting and separating edge allows vehicle parts, in particular the air conditioning heater, to be disassembled in the event of a front impact and a displacement against the instrument panel support, so that no unfavorable block formation can occur. This is advantageous if, in the case of conventional arrangements, the displacement path increased by the bent-off central region of the instrument panel carrier is exceeded.
  • the instrument panel carrier is a hollow carrier with a box profile structure and / or round profile structure in the two side regions and a triangular profile structure as a wedge profile in a central region.
  • the instrument panel support can be mounted in the body so that the wedge edge of the wedge profile points forward in the direction of travel.
  • vehicle parts in particular an air-conditioning heater, which are arranged in front of the dashboard support, are avoided in the event of a displacement by the wedge edge, which acts as a cutting and separating edge. This effect can be used in the case of an instrument panel support that runs overall in a straight line as a cross member.
  • a central area is offset from the side areas aligned in a straight line, the dashboard support being mountable such that the offset central area points rearward into the passenger compartment.
  • the free displacement path for vehicle parts in front of the instrument panel carrier can thus be increased and / or the space increased by the offset in front of the instrument panel carrier can be used for the installation of vehicle parts which can be dismantled by the spline profile in the event of a front impact.
  • the lateral end regions of the instrument panel support are expediently designed as flat box profile structures, which on the one hand advantageously creates large-area connection options on the A-pillars via the longer box profile side and, moreover, high stability can be achieved.
  • the instrument panel carrier is produced in one piece as an internal high-pressure formed part with continuous transitions between the different profile structures. This leads to correspondingly favorable, continuous force profiles in the instrument panel carrier. In addition, inexpensive production is possible.
  • instrument panel supports can advantageously be used as identical parts for different bodies, with correspondingly different fastening flange parts being provided as adapter parts, in particular for width adjustments.
  • FIG. 1 shows an arrangement according to the invention of an instrument panel carrier in a vehicle body as a schematic illustration of a view to the front left below into a partial area of the passenger compartment
  • Fig. 2 is a schematic representation of a plan view of an instrument panel support with profile cross sections.
  • the instrument panel support 1 shows an instrument panel support 1 with side areas 2, 3 and a central area 4 which is bent back into the occupant space.
  • the side regions 2, 3 with a box profile structure 5, 6 have a flatter box profile structure 7, 8 in their end regions and are connected to the A-pillars 10 of the vehicle body 11 via fastening flange parts 9 shown only on the left side.
  • a transmission tunnel 12 and a shift lever arrangement 13 are shown.
  • the central region 4 of the instrument panel support 1 has an approximately rectilinear central support part 14 which has a triangular profile 15, the wedge edge 16 of which is directed forward in the direction of travel.
  • an air conditioning heater 17 which, in the event of a front impact, is displaced together with a deformation of the front end over the existing space in the direction of the wedge edge 16 of the instrument panel support 1.
  • the instrument panel support 1 shows both a straight design of the instrument panel support 1 and a dashed design, cranked to the rear with an enlarged distance from an air conditioning heater 17 arranged in front of the instrument panel support.
  • the instrument panel support 1 has a triangular profile 15, whereas the side regions 2, 3 have box profile structures 5, 6 which merge into flat box profile structures 7, 8 in the end regions.

Abstract

L'invention concerne un agencement d'un support de tableau de bord (1) dans une carrosserie de véhicule (11) comportant des montants de pare-brise (10) sur lesquels le support de tableau de bord (1) est fixé par ses extrémités, sous forme de support transversal au niveau du tableau de bord, et comportant des éléments de véhicule (17) qui sont placés dans la zone centrale (4) devant le support de tableau de bord (1). L'invention concerne également un support de tableau de bord (1) correspondant. Lors d'une collision frontale, les éléments de véhicule (17) sont bloqués contre le support de tableau de bord (1) en raison des déformations qui absorbent l'énergie d'impact, de l'avant de la voiture. Les parcours de déformation sont alors raccourcis pour une déformation absorbant l'énergie de manière ciblée, la décélération augmente fortement de manière indésirable, et des déformations prédéterminées peuvent être affectées. Selon l'invention, le support de tableau de bord (1) s'étend dans les deux zones latérales (2, 3) en étant pratiquement aligné de manière rectiligne entre les deux montants de pare-brise (10) et, dans une zone centrale (4), en étant coudé vers l'arrière dans l'habitacle. On obtient ainsi, dans la zone centrale, un parcours de déplacement plus important pour les éléments de véhicule, sans réduire l'espace libre dans les zones latérales ni la distance devant les deux sièges avant. Dans un mode de réalisation préférée de l'invention, on utilise dans la zone centrale (4) un profilé triangulaire (15) présentant une arête cunéiforme dirigée vers l'avant, servant d'arête de séparation et de découpe.
