The air passage 31 formed by the grid perforation in the inner Longitudinal wall 5 can be through a pivotably mounted flap

35 can optionally be locked or released, such as a ■,

i comparison of FIGS. 1 and 2 can be seen.

The flap 35 is also made of an extruded profile, in particular made of light metal and has a substantially C-shaped profile cross-section.

On its upper longitudinal edge, the flap 35 has an integrally formed hook profile as a bearing part, which is attached to the inner longitudinal wall of the housing molded hook profile 37 can be pivotably suspended to the adjustment of the flap 35 between the to enable both of FIGS. 1 and 2 apparent end positions.

While the longitudinal wall 22 with its angled arms 24 and 26 forms a support element for the insulating layer 27, it is used the flap 35 as a support element for a further insulating layer profile 38. The insulating layer profile 38 is attached to the rear by two the flap 35 is held in one piece, angled arms 39 and 40, the slots each having their profile adapted 41 and <* 2 of the insulating layer profile 38 engage.

The insulating layer profile 38 has two profile legs 43 and 44 lying at an angle to one another, of which the profile leg 43 is held on the inside of the flap 35, while the profile leg 44 thereof in the direction of the stationary insulation layer 27 protrudes.

The cross-sectional shape of the insulating layer profile 38 is selected so that its profile leg 44 in the closed position of the flap 35 according to

Fig. 1 with a longitudinal edge 45 sealing against the inclined Inner surface 28 of the insulating layer 27 rests, while at the same time the free, lower longitudinal edge 46 of its profile leg 43 the inner surface of the bottom wall 3 comes to the seal support. The longitudinal edge located above the hook profile 36 of the flap 35 47 of the insulating layer profile 38 is constantly with elastic sealing pressure on the inner surface of the ceiling wall 2 or on the Support tongue 34 of the inner longitudinal wall 5.

If the flap 35 is pivoted from its closed position according to FIG. 1 into the open position according to FIG. 2, then it not only gives the from a grid perforation or the like. Existing air passage 31 in the inner longitudinal side wall 5 of the housing 1 free, but at the same time it also swivels the insulating layer profile 38 into such a position that its longitudinal edge 45 it!) by a considerable amount The dimension of the insulating layer profile 27 and its longitudinal edge 46 extend by a corresponding dimension from the inner surface of the bottom wall 3 takes off. There is then a multiple between the fixed insulating layer 27 and the movable insulating layer profile 38 deflected, slot-shaped flow channel 48 formed, which towards the outside with the slot-shaped air passage delimited between the outer longitudinal wall 4 and the further longitudinal wall 22 49 is in connection, while on the inside in a wedge-shaped upwardly tapering, between the flap 35 and the inner Longitudinal wall 5 delimited gap 50 opens.

It should also be mentioned that the outer longitudinal side wall 4 of the housing 1 is pulled down so far that its with the hook profile 20 provided longitudinal edge is flush with the lower longitudinal edge of the flange 7 of the bottom wall 3. This forms the flange 7 of the bottom wall 3, the lower end region of the outer air passage 49 off.

The relatively deep, outer air passage 49 offers a particularly good protection against the unwanted penetration of rain and snow when exposed to wind. So that decri penetration is counteracted by insects or other small life beings, a fine-meshed network can be in the outer air passage 49 or finely perforated grid 51 can be used.

From Figs. 1 and 2 it can be readily seen that the sound-absorbing Ventilation device has a relatively simple structure and a small installation cross-section. As all lengthways According to the components of the ventilation device consist of extruded profiles or molded parts, the ventilation device can also be easily adapted to any desired length.

From Figs. 3 and 4 it can be seen that the opening and closing the flap 35 can be effected with the simplest of means. A turntable 52 serves as the actuator for the flap 35, which can be inserted into a circularly delimited recess 53 of one of the two end walls 6. The turntable has 52 a radially molded actuating arm 54, which is in a In a tector-shaped manner, the recess 55 adjoining the circularly delimited recess 53 protrudes toward the interior of the room.

The turntable 52 has a lifting curve 56 running eccentrically to its center point, via which it is attached to a driving pin 57 engages, which protrudes over an end edge of the flap 35. When the turntable moves out of the position according to FIG. 3 In the position according to FIG. 4, the flap 35 is moved out of the closed position via the lift cam 56 acting on its driver pin 57 according to FIG. 1 pressed into the open position according to FIG. If the turntable 52 from the position according to FIG. 4 into the position according to Fig. 3 moved back, then engages one at the end of the lifting curve
