Problems solved by technology

Such a damping structure is not practical in car assembly because the installation of this rubber bushing is very difficult to achieve
Also, placing elastomeric isolators near the baseplate can cause problems with the aging of the elastomeric components due to the heat transferred through the baseplate from the exhaust system

Embodiment Construction

[0025] Refer to Figure 1- Figure 4 , best shows a bracket for supporting an automotive dashboard incorporating the principles of the present invention. The frame 10 extends from the vehicle floor 12 and stretches across the vehicle to support an instrument panel (not shown), and includes a cockpit cross member 15 which provides structural stability to the vehicle chassis, and a vertically extending intermediate bracket 20 . Attachment brackets 13 are welded to the bedplate 12 and provide attachment points for brackets 20 on opposite sides of a bedplate hump 19 which typically covers the transmission (not shown) and may also cover the propshaft of a rear wheel drive vehicle.

[0026] On each side of the connecting bracket 13 , a bracket 20 is connected to the connecting bracket 13 and extends upwardly therefrom to connect to the lower cockpit beam 15 and the upper cockpit beam 16 . A steering wheel (not shown) is supported on the cockpit upper beam 16 so as to receive vibrati...

Abstract

A support frame for supporting an instrument panel above a floor pan of a motor vehicle includes a support brace that is formed in two pieces that have an overlap section between them forming a lap joint in which is located an elastomeric pad to dampen the transmission of low range vibrations through the support brace to the instrument panel. The overlap section is vertically spaced above the floor pan to position the elastomeric pad away from any heat generated by a vehicle exhaust system located beneath the floor pan. The elastomeric pad may be a single piece, or may be made from several separate elastomeric segments separated by vertical spaces.The support frame of the invention can prevent the transmission of low range vibrations to vehicle parts supported by the support frame and separates the vibration reducing materials away from the bottom plate for location without changing the present assembly process.

Description

technical field [0001] The present invention relates to a bracket for supporting automotive components, and more particularly, to a bracket structure capable of damping vibration transmitted to an automotive component mounted on the bracket, such as an instrument panel. Background technique [0002] The instrument panel of the automobile is supported above the floor of the vehicle by a centrally located support brace extending upwardly from the floor ridge to connect with the middle portion of the instrument panel. Low-frequency vibrations, such as vibrations in the range of 25 to 75 Hz, are transmitted from the floor to the instrument panel through the center bracket, and the driver can feel this low-frequency vibration through the steering wheel. Although this vibration is felt by holding the steering wheel, this low frequency range vibration is generated in the chassis and is transmitted from the chassis to the cross car beam and finally to the steering wheel through the ...
