Problems solved by technology

It has been found in practice that, due to the different wall thicknesses of the housing elements, different cooling rates and pressure ratios exist, which, among other things, lead to poor-quality seams with reduced strength properties and defects in the housing elements, for example in the form of blisters Location

Embodiment Construction

[0022] figure 1 shows a transmission drive 100 according to the invention, which is used in particular as a component of a convenience drive in a motor vehicle. Within the scope of the present invention, a "comfort drive" is to be understood as an example and not in a limiting sense a seat adjustment drive, a sliding roof drive, a window lift drive, etc.

[0023] The transmission drive 100 comprises a housing element in the form of a multi-part transmission housing 10 , to which a motor housing 11 of the electric motor is flanged. Furthermore, a connecting plug 12 integrally formed on the transmission housing 10 can be seen, which is used to electrically contact or actuate the transmission drive 100 . Usually, the motor housing 11 , which is made of sheet metal (alternative: plastic), is fastened to the transmission housing 10 by means of a plurality of fastening screws 13 . In the interior of the transmission housing 10 is arranged a one-stage or multi-stage transmission, w...

Abstract

The invention relates to a housing element (10) for a transmitting-driving means (100) of comfort type driving device. The housing element (10) is basically made from plastics and is made through injection molding. The housing element (10) is provided with at least one, preferably multiple fixing positions (15, 16; 16a, 17). The fixing position is used for fixing the housing element (10) to a bearing element. The at least one fixing position (15, 16; 16a, 17) is provided with a through hole (32) for accommodating a fixing element. The at least one fixing position (15, 16; 16a, 17) is provided with a cross section (22), which is approximately ring-shaped, on a plane vertical to the through hole (32). The at least one fixing position (15, 16; 16a, 17) is connected to a preferably central area (14) of the housing element (10) by means of a connecting rib (26-28) which extends, vertical to the through hole (32).

Description

technical field [0001] The invention relates to a housing element for a transmission drive of a comfort drive system. Background technique [0002] Such housing elements are known from practice and are designed in particular as transmission housings. The transmission housing is made of plastic, in particular using glass fiber components, and is produced by injection molding. In order to fasten the housing element to a stationary support element, for example on a seat area or a roof area of ​​a motor vehicle, in practice the housing element has a plurality of pins in the form of so-called screw domes. A fastening point, which is formed in the form of a through-hole during the production of the housing element by corresponding shaping of the injection mold. In order to achieve optimal fastening of the housing element to the carrier element, the fastening points are usually arranged at least partially in the corner region of the housing element. [0003] The (injection) mold...
