DE10130043B4 - Instrument panel for a vehicle, in particular for a motor vehicle, with attached instrument panel - Google Patents

Abstract

The invention relates to an instrument panel (1) for a vehicle, in particular for a motor vehicle with an attached instrument hood (2). The instrument panel (2), designed as an individual part, is mounted on the instrument panel (1) so that it is yielding due to a force impulse impinging on it. Such a force pulse can z. B. arise in a collision of the vehicle and a resulting axial displacement of the steering wheel rim (4) in steering column direction (3). The flexibility of the instrument guard (2) does not restrict the travel of the steering column, thus increasing occupant safety.

Description

The invention relates to an instrument panel for a vehicle, in particular for a motor vehicle, with attached instrument scoop according to the preamble of claim 1.

In almost all motor vehicles are a plurality of display instruments in the instrument panel, which are usually arranged on the driver side. In many embodiments, these gauges are combined into a cluster instrument. To the reading for the driver of the essential indicating instruments of a motor vehicle, such. As speedometer with odometer, tachometer or fuel gauge and various indicator lights to facilitate, these are usually arranged perpendicular to the line of sight of the driver before this.

In order to avoid reflections with the front of the windshield of the motor vehicle in the display instruments, they are integrated in the instrument panel, that over the display instruments a scoop is arranged. This ensures a perfect reading of the display instruments by the driver of the motor vehicle.

In general, a distinction must be made between two embodiments of an instrument cover. First, there is the possibility of integrating the instrument panel in the instrument panel, so that the whole is only one component or secondly perform the instrument panel as a separate component and is mounted only in the course of the assembly process of the motor vehicle. The decision on one of the two options is usually determined only by technical tool or designerische specifications.

In the case of an instrument hood designed as a separate component ( DE 198 07 317 A1 ) are in the interpretation of size and position of the same usually only the ergonomic guidelines in driving in the foreground. The connection of the instrument panel to the instrument panel is designed as a solid, rigid connection.

From the WO 00/17035 A An arrangement for a dashboard is known in which a movable instrument scaffold is coupled to a crash sensor. In an accident, a traction device is activated via the crash sensor, which pulls the instrument cover away from the steering wheel, that is, moves away from the steering wheel. Such an active system is very expensive.

The DE 196 10 282 A describes a knee-joint assembly with a knee-skirt which is attached below the dashboard to this. On the knee shell shell more deformation elements are mounted on a support, which support the knee shell on the vehicle body. The knee cup should break off at a knee impact on one of their brackets at designated notch sites to avoid excessive knee loads.

In the DE 31 28 785 A a dashboard panel with predetermined breaking points is shown, which has a damping effect on the impact of the driver on the steering wheel. For this purpose, a piece of the panel of the dashboard in the area of the steering column is surrounded by predetermined breaking points. In a crash-induced displacement of the steering column break these, so that the steering wheel is further displaced forward.

The DE 21 26 666 A describes a safety steering system for motor vehicles with a safety device which is arranged in the form of a plastically deformable front wall part and compliant intermediate pieces on the steering wheel so that it is deformed in a collision of the driver on the steering wheel and thus absorbs part of the impact energy.

There are more and more motor vehicles equipped with steering columns, which are axially displaceable in the steering column direction. This means that in the event of a collision of the motor vehicle, the steering column with steering wheel rim is pulled forward to thereby increase occupant safety. It may also come to a contact between the steering wheel rim and Instrumentenutze. The force impulse thereby transmitted to the instrument scaffold can lead to a restriction of the steering column movement in a rigid connection of the same to the instrument panel, which in turn can adversely affect the occupant load. Likewise, a destruction, z. B. Fragmentation, the instrument scabbard are not excluded.

The object of the invention is to provide an instrument panel for a vehicle, in particular for a motor vehicle, with attached Instrumentenhutze, with the aforementioned disadvantages are avoidable as possible.

This object is achieved with the features of claim 1.

According to claim 1, the novel instrument panel for a vehicle, in particular for a motor vehicle, an attached, executed as a separate component instrument scraper, which is arranged on the driver side in front of a steering column in the steering column direction axially displaceable. The connection of the instrument panel to the instrument panel is designed compliantly. When the steering wheel rim is displaced axially in the direction of the steering column and the resulting contact between the steering wheel rim and the instrument hood is removed, the instrument cover is displaced or folds away by the resulting force impulse which is transmitted to the instrument cover. As a result, there can be no restriction of the steering column movement more, since the scoop can dodge accordingly. Furthermore, this dodging of the scoop also significantly reduces the risk of uncontrollable fragmentation, which in turn increases the safety of the vehicle occupants.

In order to ensure a defined and reproducible response of the instrument panel to the force impulse transmitted by the steering wheel rim, the connection between instrument panel and instrument panel is preferably designed as a defined predetermined breaking point.

In various embodiments, the transmitted from the steering wheel rim force pulse z. B. lead to a shift of the instrument cover and / or to fold away the instrument cover. This can be achieved with different versions of the connection between instrument panel and instrument panel.

The different forms of connection of the instrument panel to the instrument panel can, for. B. be executed as Verclipsungen or as glands.

A particular preferred embodiment provides that the instrument scaffold is free of damage after contact with the steering wheel rim and the force impulse transmitted thereby, resulting in a positive influence on the repair costs of the previous collision.

Reference to a drawing, the invention is explained in detail.

Show it:

1 a schematic section through the entire arrangement in normal position of the steering wheel rim,

2 a schematic section through the entire assembly, wherein the steering wheel rim contacts the Instrumentenhutze, and

3 a schematic section through the entire arrangement with shifted instrument scaffold.

In 1 are the instrument panel 1 and the instrument scoop 2 in its normal position to the steering wheel rim 4 shown. The distance between the instrument scaffold 2 and the steering wheel rim 4 is usually designed only from an ergonomic point of view of driving. The steering wheel rim 4 is at a steering column direction 3 axially displaceable steering column mounted.

After a potential collision of the motor vehicle, the steering column is in the steering column direction 3 shifted to increase occupant safety thereby. This leads to a contact (see 2 ) between the steering wheel rim 4 and the instrument scoop 2 , This is a power pulse on the instrument 2 transfer. Through a defined breaking point 5 is the connection between instrument scaffold 2 and the instrument panel 1 solved.

3 shows the instrument scoop 2 after that from the steering wheel rim 4 transmitted force pulse. This was the instrument scoop 2 shifted and so the movement of the steering column no longer restricted. A possible destruction of the instrument scaffold 2 as with a rigid connection to the instrument panel 1 is given, is thus excluded. This increases the safety of the vehicle occupants.
