Description

Headrest for head Technical Field The present utility model relates to a headrest. Such a headrest has a holding device for supporting on a vehicle seat, which is fixedly or relatively movably connected to a base of the headrest. Such a holding device is for example a carrier bar or a carrier bar collar. Background The height adjustment may be achieved, for example, in that the holding device is adjustable relative to the vehicle seat or, alternatively, the base is adjustable relative to the holding device. The headrest can thus be set into different height positions. The head rest is fastened directly on the base or guided adjustably in the horizontal direction on the base, for example. A seat with a headrest is known from DE 10 2019 117 990 A1. The backrest of the seat has a load bearing system. A carrier element comprising a mounting section 42 and a guide 44 is assigned to the head abutment. The mounting section 42 is arranged in a stationary manner on the carrier system. The head rest is mounted in the guide in a movable manner and can be locked in a set position. US 8,573,693 B2 relates to a child seat for a vehicle. The seat is essentially two-part and comprises a lower seat part, on which the first guide and the first locking means are formed, and a second seat part, to which the head rest is assigned and which has the second guide and the second locking means. Disclosure of utility model The aim of the utility model is to provide a headrest with a height adjustment, which can be produced at low cost and which is designed to be narrow in the rear region of the headrest. This task is solved by the headrest of the present utility model. The utility model relates to a headrest having a base on which a head rest is held, and having a retaining device by means of which the base can be supported on a vehicle seat, wherein the base can be adjusted in height relative to the retaining device, wherein the retaining device comprises at least one central carrier part which is configured as a molding, wherein the guide means for supporting and guiding the base along a guide rail comprise a first guide means assigned to the carrier part and a second guide means assigned to the base, such that the base has only a degree of freedom in the direction along the guide rail and the base can be fixed in a set position relative to the carrier part by means of a fixing device, wherein the carrier part is configured as a polygon, a circle, an ellipse or a C-shape in cross section about a longitudinal center axis, and the carrier part has a slit parallel to the longitudinal center axis. The headrest includes a base on which the head rest is held. The head rest can be fastened immovably to the base or can be formed in one piece therewith, or the head rest can be supported on the base in an adjustable manner in the x-direction, for example. The base can be supported on the vehicle seat by a retaining means of the headrest. The holding device is supported, for example, on the structure of the backrest. The base is height-adjustable relative to the retaining means. This means that the base can be adjusted relative to the holding means in such a way that its vertical position changes. The holding device comprises at least one central carrier part. The guide means for vertical adjustment comprise a first guide means assigned to the carrier part and a second guide means assigned to the base part. The first guide means is configured to support and guide the base along the guide rail such that the base has only degrees of freedom in opposite directions along the guide rail. The carrier part comprises, for example, form-locking means as guide means, which prevent a movement of the base part that differs from a movement on the movement track. In the set position, the base can be fixed relative to the guide rail by means of a fixing device. That is, when the fixing device is fixed, the base is held in the set position. The term "fixed" is to be understood in the broadest sense herein and may mean, for example, self-locking of the drive as well as locking. The carrier part has, for example, a holding region and a guide region. The holding region serves to support the carrier part directly or indirectly on the vehicle seat. The guiding region comprises first guiding means for guiding the base. For example, a further support or holding device for supporting the drive device for adjusting the base can be formed on the guide region or on the holding region. The carrier part has at least one region which forms a guide rail and which is configured, for example, in a circular, oval or quadrangular manner in cross section with respect to the longitudinal center axis, wherein the carrier part can have a slot which runs parallel to the longitudinal center axis. Thus, the bearing member has high stability and can restrict the degree of freedom in allowing the base to move in a direction other than the movement track. The carrier member is, for exam
