Abstract: The invention relates to a self-supporting articulated-arm cassette awning, in particular for motor homes or trailers, comprising articulated arms (20) that are pivotable at awning arm joints or shoulder joints (10), and brackets or shoulders (II) for connecting the entire awning (100) to the vehicle by means of fastening elements and for receiving joint pins (I) in an insertable, in particular, slidable manner and for at least limiting the twistability of joint pins (I) of those parts of the awning arm joint or shoulder joint that are fixed to the vehicle. Desirable is a compact, continuously variable twisting arrangement for the joint pin which, at the same time, is capable of absorbing the high torques of the extended awning.

Abstract: The invention relates to a service unit for vehicle air-conditioning systems, which is provided with an emptying and filling device for removing the coolant or a coolant/compressor oil mixture from a vehicle air-conditioning system and replenishing the vehicle air-conditioning system with coolant and optionally with compressor oil. The device can include at least one tank for coolant and a vacuum pump for generating a negative pressure in the vehicle air-conditioning system emptied of coolant or coolant/compressor oil mixture for a subsequent intake of coolant and optionally compressor oil into the vehicle air-conditioning system to be replenished. A chimney-like gas-collecting chamber having upper and lower openings can be arranged inside the service unit and is otherwise sealed off from the surrounding atmosphere.
