description

The innovation relates to a filter for supplying fresh air to the passenger compartment in vehicles.

It is known in ventilation systems for the passenger compartment of motor vehicles. providing air filters in the Luftansaugschächten with blower, soft to the section of betreffehden Änsaugschachtes correspond to what is done by inserting appropriate filter packets into the suction intake ducts * This i $ \ access and replacement of the filter difficult and only to those skilled possible.

It is now the task of the innovation to provide a remedy and an easily connectable and replaceable filter to accomplish. For this purpose, the filter according to the innovation according to the preamble of claim 1 is characterized by that the usual / Äufsatzgitter is followed by a housing pot in which a network is stretched on the connection side, while a removable bar grille on the inlet side, in particular two crossing bars, which on the one hand Housing can be pushed through and, on the other hand, screwed in, for exchanging the filter layer (s) to be introduced between the net and the bars.

In this case, the attachment grille is expediently arranged in a connection piece to which the housing pot with tensioning network on the one hand and removable rod grille on the other hand

With the interposition of the filter layer (s) follows.

Another idea of the innovation is in the connection piece between the grille and tension net A flap that can be opened and closed is provided on the circumference for introducing fragrance carriers. So you can into the air intake in a simple manner E.g. in cologne or a cotton ball dipped in an inhalation liquid for refreshment or

bring against colds and the like. |

This filter attachment can also be used as protection against pollen allergies to prevent pollen from entering the passenger compartment. Finally, in the filter too an activated carbon and / or Chtmie filter in addition be used to achieve protection against exhaust gases and other toxic or radiation substances.

A preferred embodiment of the innovation is shown, for example, in the drawing and described below, namely show:
