  • Patent number: 5179759
    Abstract: A drive mechanism for a motor vehicle windshield wiper device has a crank which is driven in a rotating manner and produces a pivoting movement of a windshield wiper via a drive rod. If the movement of the windshield wiper is obstructed by a snow wedge building up in the wiper socket, the drive mechanism provides for an obstruction evading movement of the drive rod in such a way that the crank can fully rotate unimpeded. In order to obtain a low loading of the drive rod and its joints in the event of obstruction of the windshield wiper and to obtain a uniform wiping zone in normal wiping operation, the novel drive mechanism for the drive rod is firmly coupled to the crank and a lost motion drive means is arranged on the wiper shaft.

  • Patent number: 5050486
    Abstract: In an air-conditioning system for vehicles, with a blower, evaporator, heat exchanger and air distributor box with air-outflow ports for at least one middle nozzle and for side nozzles, the air distributor box is connected directly by means of its inlet cross-section to the evaporator. The heat exchanger is arranged aproximately centrally in the air distributor box so as to subdivide the latter into a front and a rear space portion. An air-guide connection piece extends from the front space portion which leads to the middle nozzle and which is connected to the front space portion via a cold-air scoop flap and is in communication with the rear space portion via two bypass channels, in each of which a temperature control flap is arranged. Air-outflow ports for the side nozzles are arranged in the bypass channels. Thus, in the "maximum cooling" mode, cold air passes directly from the front space portion of the air distributor box into the middle and side nozzles and improves the cooling of the passenger space.

  • Patent number: 5050487
    Abstract: In a heating/air conditioning system for a motor vehicle, with an exchangeable and selectively bypassable absorption filter which is arranged in a channel shaped housing and through which fresh air and/or circulating air can flow, a high degree of absorption is achieved when unprocessed air passing through internal leakage points at the absorption filter holder and the shut off bypass line of the absorption filter is collected and conveyed, via at least one line, to a location which is separated from the passenger space and the pressure level of which is lower than the pressure level on the flow off side of the absorption filter. Untreated air, which in certain circumstances escapes through external leakage points of a housing partition, is guided outside the passenger space, at the same time being prevented from overflowing into the latter.

  • Patent number: 4779517
    Abstract: A fresh air supply device is disclosed which is connected upstream of a blower of a heating or air conditioning unit in a motor vehicle. The blower is accommodated by a housing with the fresh air entering into a gap between the windscreen and the adjacent hood. The fresh air is deflected while water and foreign bodies are separated and is supplied to a filter underneath the hood. The filter can be exchanged by pulling it out upwards. Downstream of the filter, the air enters the intake side of the blower. In order to prevent unintentional heating up of the fresh air in the intake tract, while retaining easy exchangeability of the filter, the filter is covered by an intake scoop which can be moved away and is thermally shielded relative to the vehicle hood or bonnet.
