Abstract

The invention relates to an air guidance system having an air guidance housing and an air passage grating fastened thereto, the air passage grating being held on the air guidance housing by means of a snap-lock connection. In order to simplify maintenance of such an air guidance system it is provided according to the invention that the air passage grating carries at least one latch having a snap-in shoulder that can be engaged in a snap-lock seat of the air passage grating and that the air passage grating pivotally accommodates a handle in a bearing seat, said handle disengaging the latch from the snap-lock seat when set from the locking position to the unlocking position.

First claim

The invention claimed is:

1. An air guidance system having an air guidance housing and an air passage grating fastened thereto, the air passage grating being held on the air guidance housing by means of a snap-lock connection, wherein the air guidance housing carries at least one latch having a snap-in shoulder that can be engaged in a snap-lock seat of the air passage grating and the air passage grating pivotally accommodates a handle in a bearing seat, said handle disengaging the latch from the snap-lock seat when set from the locking position to the unlocking position such that the air passage grating may be moved apart from the air guidance housing, and wherein the handle carries two bearing tabs forming a common bearing axis which respectively are engaged in the bearing seat,
Wherein the handle comprises at least on actuator element forming an approach slope which interacts with a slope of the snap-in shoulder for disengaging the snap-in shoulder such that the snap-in shoulder is deflected,
Wherein the air guidance housing carries at least two latches which can be disengaged by means of a respective associated actuator element when operating the handle,
Wherein the handle has a press-off piece spaced apart from the pivot axis of the handle, and the press-off piece can be pressed on a press-off face of the air guidance housing for pressing off the air passage grating from the locking position.

2. The air guidance system of claim 1 , wherein the handle comprises a stopper abutting at a locking piece of the air passage grating in the unlocking position of the handle.

3. The air guidance system of claim 1 , wherein the air passage grating is pivotally coupled to the air guidance housing by means of a hinge connection.

4. The air guidance system of claim 1 , wherein the bearing seat comprises snap-lock elements configured such that when the bearing tabs have passed the snap-lock elements and reach the bearing seat, the snap-lock elements snap behind the bearing tabs so that the handle is securely held to the air passage grating.
