Definitions
- the invention relates to a head restraint arrangement for a vehicle seat.
- the headrest cushion In the case of vehicle seats with a height-adjustable headrest, the headrest cushion is generally guided in a height-adjustable manner via headrest rods in guide bushes of the backrest.
- height adjustment forms between the headrest pad and the backrest edge ver Sli ⁇ cher gap, which can increase the risk of injury to the seat occupant in his head, neck and Schulterbe ⁇ rich in an accident, especially a rear-end crash.
- DE 196 14 314 A1 and DE 101 11 653 A1 show vehicle seats with a backrest, in which a headrest area is integrated into an upper backrest part.
- the entire upper backrest part with the head receiving cushion area and the shoulder receiving cushion area can be adjusted in height.
- a separate adjustment of the Kopf ⁇ support for individual adaptation to the respective Wegi ⁇ sassen is not possible.
- the invention is based on the object to provide a headrest assembly for a vehicle seat, which ensures individual adjustability and high comfort with high crash safety.
- the dependent claims describe preferred developments.
- the invention is based on the idea of preventing the formation of the variable gap between the headrest and the upper edge of the backrest by means of a flexible headrest cushion, with its front end being fixed to the backrest and changing its shape when adjusting the height.
- the flexible head restraint pad slides on the adjusting element, changing its shape, whereby in particular its upper curvature range can shift; This results in a combined rolling and sliding movement.
- suitable materials eg.
- the friction occurring in this case can be kept low.
- the adjusting element can be formed with a uniform radius of curvature at its upper region of curvature, so that the upper curvature region of the headrest cushion moves with a low resistance during the rolling movement.
- According to the invention can thus be a gap-free connection of the headrest to the backrest, which allows a uniform recording of the head, neck and shoulders of the seat occupant and significantly reduces the risk of injury in this area.
- the rear end of the headrest can advantageously be biased downwardly to ensure a smooth, firm abutment on the control element and a defined shaping.
- the height adjustment can be done via a rack-and-pinion mechanism, which can be operated by hand or electric motor.
- FIG. 1 shows a longitudinal section through a vehicle seat with a headrest arrangement according to the invention and a seat insert with the headrest partially extended;
- FIG. 2 shows a representation corresponding to FIG. 1 without seat occupants
- Fig. 3 is an enlarged detail of the headrest assembly and the upper part of the backrest of Figure 2;
- FIG. 4 shows an illustration corresponding to FIG. 1 in the case of a retracted, lower position of the headrest with seat occupants
- FIG. 5 shows the illustration from FIG. 4 without seat occupants
- FIG. 6 is an enlarged detail of the headrest assembly of Figure 5.
- a vehicle seat 1 has a seat frame 2 which can be fastened to the vehicle chassis, a seat cushion 3 and a backrest 4.
- a headrest 5 is provided, which has a hollow box 6 serving as a control element according to the invention and a headrest pad 7.
- the z. B. made of plastic hollow box 6 is height adjustable via at least one, preferably two headrest rods 8.
- the headrest rods 8 are formed as racks, each with a toothing 9, in which a stored in the backrest 4 pinion 10 engages, via a handwheel or an electric drive for height adjustment of Hollow box 6 is driven.
- the head restraint rods 8 are guided in a height-adjustable manner in guide sleeves 11 accommodated in the backrest 4.
- the headrest pad 7 is elongated and flexible and placed over serving as an actuator hollow box 6, so that its front end, 19 and its rear end 20 each hang down.
- the front end 19 is received in a shoulder 18 of the backrest 4, so that the front sides of the backrest 4 and the headrest pad 7 terminate substantially flush.
- the headrest pad 7 has a padding element 12, which is surrounded by a headrest cover 14, which is sewn at its front lower end with a backrest cover 16 ofani rest 4 in a seam 17; This results in the front of the backrest 4 is a substantially smooth transition to the headrest. 5
- the rear end 20 of the headrest pad 7 is additionally spring-biased towards the bottom.
- a tension spring 22 is provided between a spring connection 25 at the rear end 20 of the headrest pad 7 and a spring connection 24 of the backrest 4.
- the hollow box 6 is adjusted vertically via the headrest rods 8. Since the headrest pad 7 is attached at its front end in the seam 17 on the backrest cover 16 ofani ⁇ rest 4, it slides with his headrest cover 14 on the hollow box 6.
- the headrest rods 8 are adjusted with the hollow box 6 down so that the rear end 20 of the headrest pad 7 is pulled by the tension spring 22 downwards; in the lowermost position shown in FIGS. 4 to 6, the head restraint pad 7 lies on a step 26 of the backrest 4 on, or there is only a small distance to the step 26 to ensure a flush connection.
- the cushion element 12 thus performs a Abroll ⁇ movement, the headrest cover 14 on the hollow box 6 glei ⁇ tet.
