Control unit for component i.e. ventilation, heating and/or air-conditioning component, of vehicle, has latching projection formed as rolling body with peripheral region, where rolling body is formed of sound-absorbing material at region

摘要

The control unit has a latching device (26) including a latching element (24) with a latching projection (18) and another latching element (28) with a latching depression (20) for accommodating the latching projection. The latter latching element is latchingly connected with the former latching element. The latching projection is formed as a rotatably mounted rolling body i.e. two-component injection molding part, with a peripheral region touching the latching depression. The rolling body is formed of a sound-absorbing material at the peripheral region. The rolling body includes a core made from a plastic or metallic material. The insulation elastomer material is mounted on the core of the rolling body and formed as ethylene propylene diene monomer and thermoplastic elastomers materials. The rolling body is selected from roll, wheel or ball type rolling bodies.
