Definitions

  • the invention relates to a headrest for seats, in particular vehicle seats, which is arranged in the end region of a backrest and has a support and / or catch element made of preferably compressible material, the support and / or catch element being formed at least in two parts and having a first part, which is connected to the backrest.
  • Headrests of this type are known in particular in vehicle seats and are an indispensable safety feature today which is intended to prevent injuries in rear-end collisions, for example whiplash injuries, by overstretching the neck area.
  • Headrests are known which are formed in one piece with a backrest of the seat as so-called frame headrests.
  • headrests are known which are adjustable in their distance from the backrest, so that they can be adjusted in their setting to different sizes of the people sitting on the seat.
  • these headrests can also be adjusted in their inclination relative to the head of the person sitting on the seat in order to adjust the distance between the head and the headrest in order to optimally prevent the injuries.
  • headrests are known which, due to their articulation on the backrest, are automatically movable in the direction of the head to be caught in a rear-end collision.
  • Such headrests have proven themselves from a safety perspective. They are sufficiently comfortable even while driving. However, if the seat is used for relaxation during a break, it can be determined that the headrest is too far away from the head of the person resting on the seat, especially when the backrest is adjusted to the rear. The neck area is therefore stretched in the rest position, which can result in muscle tension.
  • a generic headrest for seats is known from EP 1 142 753 A1.
  • This headrest which is arranged in the end region of a backrest, has a support and / or catch element made of preferably compressed siblem material on.
  • the support and / or catch element is designed in two parts, two cheek-like elements connected to one another being pivotable relative to a first part such that they laterally guide or hold a head resting on the headrest.
  • the two cheek-shaped elements are connected to one another via a central web, so that overall they form a U-shaped element which can be pivoted about an axis of rotation which is arranged on support elements of the headrest which connect the headrest to the vehicle seat.
  • a neck bed for a headrest which is designed in a neck and upper back supporting shape and can be used flexibly for all types of vehicles with and without headrests.
  • This neck bed can be attached to the lower area of the headrest using a Velcro connection, for example.
  • push buttons can be provided.
  • the invention is based on the object of further developing a generic headrest in such a way that it offers both the necessary safety aspects while driving and sufficient comfort during a rest phase.
  • the solution to this problem provides that the support and / or catch element is arranged on the first part such that it can be pivoted such that the second part is adjustable from a position congruent with the first part into a position arranged below the first part, in which the second part is arranged completely below the first part.
  • a headrest designed in this way offers the known high level of security against the above-mentioned injuries in rear-end collisions, while in the second position, a comfortable relaxation posture by supporting the neck area with the second Part of the headrest can be taken.
  • the first part In its area facing the backrest, the first part preferably has an axis of rotation on which the second part is arranged so as to be pivotable between the two positions.
  • This embodiment has the particular advantage that the headrest is very easy to use. To take the rest position, it is only provided that the second part is detached from the first part and folded down about the axis of rotation, as a result of which the second part comes to rest on the upper section of the backrest, for example. In this position, the contact surface of the headrest is also doubled compared to the first position, which also results in an increase in comfort for the person occupying a rest position.
  • the distance of the first part from the backrest is adjustable.
  • the second part of the headrest can be connected to the first part in the position congruent with the first part.
  • the connection of the second part to the first part can preferably be formed by a connecting device, for example designed as a Velcro fastener, the Velcro fastener consisting, in a manner known per se, of two elements, one of which is a first element on the first part and a second element is on the second part of the Headrest is arranged.
  • a push button system can be provided, for example, which consists of at least two push buttons, which in turn can be arranged in the area of the two parts or on the one hand on the first part in the upper area or in the rear area and on two tabs of the can be attached to the second part, which tabs can be guided over the first part of the headrest in order to be able to connect the two snap button halves there.
  • the distance from the first part can be adjusted in the position arranged below the first part. This adjustment option also serves to individually adapt the headrest to the person sitting on the seat during the resting phase.
  • the first part preferably has a recess for receiving the second part, in order to form an overall headrest which corresponds to the customary shapes.
  • the recess is concave.
  • the second part has two main surfaces which have an essentially matching curvature and are convex.
  • At least the second part consists of a compressible foam core and a cover corresponding to an upholstery of the seat.
  • This configuration ensures the possible adaptation of the headrest to different upholstery in vehicles, so that, for example, retrofitting of already existing vehicle seats is also possible in a simple manner.
  • this configuration can be adapted in a simple and cost-effective manner to different upholstery fabrics with, for example, different materials, such as leather, synthetic leather or fabric, and with different designs.
