## Abstract

A hinge comprises a hinge part, which can be secured on a door of the shutter and is mounted on a side part such that it can be pivoted via a carrying lever and a guide lever, also comprises at least one spring, by means of which the hinge part, in a self-retracting region of the hinge, is prestressed into a closed position, and further comprises a linear damper with a piston rod, which can be moved relative to a damper housing and is intended for damping a closing and/or opening movement of the hinge part, wherein a deflecting element is provided, said deflecting element being mounted on the side part such that it can be rotated about an axis and being arranged between the damper and the guide lever so that, during a closing movement of the hinge part, it moves the damper in order to generate a damping force, wherein, during an opening movement of the hinge part, the deflecting element moves the damper in order to generate a damping force before the fully open position of the hinge part has been reached. This makes it possible to avoid hard impact of a door in the opening direction.

## Claims

### Claim 1

A hinge comprising:
a hinge part pivotably mounted to a side part by a guide lever and a support lever;
at least one spring configured to pretension the hinge part in a closed position with respect to the side part in a self-retraction range of the hinge;
a linear damper having a damper housing and a piston rod movable in relation to the damper housing;
a deflection element rotatably mounted about an axis on the side part; and
a lever pivotably connected to the guide lever and to the deflection element;
wherein the guide lever, the support lever, and the lever cooperate to rotate the deflection element in a first direction in response to rotation of the hinge part in a closing direction, thereby moving the piston in a first direction with respect to the damper housing to generate a damping movement during a closing movement of the hinge part; and
wherein the guide lever, the support lever, and the lever cooperate to rotate the deflection element in the first direction in response to rotation of the hinge part in an opening direction, thereby moving the piston in the first direction with respect to the damper housing to generate a damping movement during an opening movement of the hinge part.

### Claim 2 (depends on 1)

The hinge according to claim 1, wherein the opening damping is active at least in an angle range of at least 10° before the maximally open position of the hinge part.

### Claim 3 (depends on 1)

The hinge according to claim 1, wherein the deflection element executes a pendulum movement during a movement from the completely closed position of the hinge part into the completely open position of the hinge part.

### Claim 4 (depends on 3)

The hinge according to claim 3, wherein the movement direction of the pendulum movement of the deflection element during a movement from the completely closed position of the hinge part into the completely open position of the hinge part reverses between the closing damping range and the opening damping range.

### Claim 5 (depends on 1)

The hinge according to claim 1, wherein the movement of the piston rod of the damper during the closing damping is greater than the movement of the piston rod of the damper during the opening movement.

### Claim 6 (depends on 1)

The hinge according to claim 1, wherein the stroke of the damper during closing damping is greater than the stroke of the damper during opening damping.

### Claim 7 (depends on 1)

The hinge according to claim 1, wherein the rotatably mounted deflection element is articulated with the damper or a component coupled to the damper.

### Claim 8 (depends on 1)

The hinge according to claim 1, wherein the deflection element is articulated with the guide lever or a component connected to the guide lever.

### Claim 9 (depends on 1)

The hinge according to claim 1, wherein the damper is a compression damper, which generates higher damping forces during the relative retraction of the piston rod into the damper housing than during the extension of the piston rod out of the damper housing.

### Claim 10 (depends on 1)

The hinge according to claim 1, wherein the damper is a traction damper, which generates higher damping forces during the relative extension of the piston rod-out of the damper housing than during the retraction of the piston rod into the damper housing.

### Claim 11 (depends on 1)

The hinge according to claim 1, wherein the at least one spring pre-tensions the hinge part in an opening direction in a self-opening range, wherein the at least one spring pre-tensions the hinge part in a closed position in the self-retraction range of the hinge.

### Claim 12 (depends on 1)

The hinge according to claim 1, wherein the opening damping is active at least in an angle range of at least 20° before the maximally open position of the hinge part.
