Abstract: A closure device includes a first closure part which has a body, and a second closure part. A locking element and an engagement portion in a closing position are mutually engaged in such a manner that the first closure part and the second closure part are locked to one another. The first closure part has a first magnetic installation, and the second closure part has a second magnetic installation, said first magnetic installation and said second magnetic installation when placing the first closure part and the second closure part against one another interact in a magnetically attractive manner. The at least one locking element is magnetically configured in such a manner that the at least one locking element in the closing position by way of the first magnetic installation and/or the second magnetic installation is loaded in the direction of engaging with the at least one engagement portion.

Abstract: A fastener device includes a first fastener part and a second fastener part which can be mounted on one another along a closing direction and are held against one another in a closed position, and are releasable from one another in order to open the fastener device. The second fastener part has a winding element on which a tension element can be arranged and which is rotatable relative to the first fastener part in order to wind up the tension element on the winding element in a winding direction.

Abstract: It is provided a closure device includes a first closure part and a second closure part, which can be placed against each other along a closing direction, are held against each other in a closed position, and can be detached from each other for opening the closure device. The second closure part includes a housing element with a bearing opening and a rotary element rotatably mounted in the bearing opening of the housing element. The rotary element is operatively connected to an actuator element and can be rotated with respect to the second closure part for adjusting the actuator element along a winding direction. The first closure part includes a first toothing device the second closure part includes a second toothing device, and in the closed position of the closure device the first toothing device and the second toothing device are in engagement with each other in such a way that the first closure part and the second closure part are positively held against each other along the winding direction.

Abstract: A chair includes a seat and a seat mechanism, the seat being coupled to the seat mechanism in such a manner that the seat is, in a front end region, pivotably supported about a first axis of rotation orientated parallel with the axis of a user's knees. In its front end region, the seat is also supported on the seat mechanism so as to be rotatable about a second axis of rotation orientated perpendicularly to the first axis of rotation.
