摘要:
A vehicle passenger, or the like headrest equipped with an arrangement to secure an end position is disclosed. In order to accommodate removal of the head rest with both hands after the cancelling of a locking effect, a remote control is provided in the form of an operating rod extending approximately in axial direction of a headrest support rod. When the operating rod is operated, the catch is guided into a secured disengaged position which, when the support rod is pushed in again, by the effect of the support rod, is cancelled again so that safety is not sacrificed.

A guide means for a support bar of a vertically slidable headrest of which the two guide elements, made of resilient material and inserted mutually superposed at an interval in a guide rail, are in mutual communication by a web in a manner favorable for production and assembly and wherein a median section of the web serves as a further bracing point for the support bar in addition to the two guide elements.

In the case of a seat, particularly a vehicle seat having a supporting frame, there is provided a spring system that is fastened at said supporting frame, an upholstered part that rests on said spring system, and a cover that covers said upholstered part, and for achieving a shaping tension of the upholstery, is braced in its border area in the direction of the supporting frame. The cover, in order to achieve a soft surface, is fixed a first time in the transition area from the upholstered part to the spring system, in which case this area receives a bearing capacity created by stiffening means, such as the surrounding frame, the seat shell or the dimensionally stable upholstery material, said bearing capacity being capable of absorbing the preloading forces introduced via the lower cover portion, without repercussion on the area of the upholstered part that is on the side of the seat surface.

A cushioning for a vehicle seat has a cushioning layer and a ventilation layer which covers this cushioning layer and through which air flows. A plurality of air ducts completely penetrate the cushioning layer and are open on the backside of the cushioning layer and in which one miniature fan respectively is arranged for blowing air into the ventilation layer. For ventilating cushioning areas which, because of sitting aids arranged in the cushioning layer, are not suitable for a direct ventilation, the end of the air ducts assigned to these cushioning areas which faces the ventilation layer is constructed such that a portion of the air flow penetrating the air duct enters into the open cross-sectional surface of the ventilation layer.

A vehicle seat has a cushion integrated in a seat part and/or a backrest, which cushion has a ventilation layer, through which air can flow, and an air-permeable cushion cover spanning the cushion surface. The seat also has at least one ventilator arranged below the cushion for blowing air into the ventilation layer. In order to provide a ventilated vehicle seat construction at reasonable cost for vehicles of the medium to lower price range, the ventilation layer is constructed as an air-permeable cushion support which rests on a cushion carrier only by way of intermediate placement of an air-impermeable pressure distribution layer. The pressure distribution layer has at least one inflow opening for the ventilation air on which the ventilator is arranged below the air distribution layer.

A seat test body is provided for vibration measurements. In order to be able to obtain, during vibration measurements in the whole spectral range, measuring results which can be compared at least qualitatively with corresponding test person measurements, the buttocks imitation and the back imitation of the seat test body are each formed by padded hard parts. The hard parts of the buttocks imitation and those of the back imitation imitate true to life the corresponding bone structure of a human skeleton at least with respect to the portion of the skeleton which is loaded during sitting. With respect to the layer thickness, the softness, the elasticity and the damping behavior as well as the local distribution of these parameters, the padding of the hard parts anthropomorphically imitates the soft parts in the buttocks area and the back area. For achieving the required sitting weight of the seat test body, a passive ballast in the form of several weights is placed on the interior side into the buttocks imitation and/or is placed on shelf-type consoles on the interior side of the back imitation. Relative to the buttocks imitation, the back imitation is disposed to be swivellable within a limited angular space about the hip joint point and is elastically prestressed in the sense of a stretched position of the back part and the buttocks part.

A vehicle seat having seat and backrest cushions includes a ventilation device for ventilating the cushions as well as a heating device for heating the cushions. A desirable sitting climate providing high comfort is produced by eliminating both a seat user's perspiration and overcooling. The desirable sitting climate is assured by a control unit which is connected on an input side with a temperature sensor arranged in a cushion and on an output side with the electric circuits of the ventilation unit and the heating unit. The control unit is adjusted such that, at cushion surface temperatures measured by the temperature sensor which are above an indicated value, it switches on the ventilation device or changes it to a higher power stage and/or switches off the heating device or changes it to a lower heating capacity. At cushion surface temperatures which are below the indicated value, the control unit switches off the ventilation device or changes it to a lower power stage and/or switches on the heating device or changes it to a higher power stage. The control unit may also operate based on an output from a moisture sensor.
摘要:
A vehicle seat has a cushion integrated into a seat part and/or a seat back. The cushion has a ventilation layer through which air can flow and a cushion cover stretched over the cushion surface facing the seated individual. A plurality of electrically driven miniature fans which are located in air channels to blow air into the ventilation layer that terminate at the underside and rear of the cushion facing away from the cushion cover are provided. The air channels extend up to the ventilation layer. To optimize the ventilation efficiency of the seat ventilation, exhaust air channels are provided in the cushion that extend from the ventilation layer up to the underside or rear of the cushion and terminate freely there.

A vehicle seat has a cushion integrated in a seat part and/or in a backrest. The cushion has a ventilation layer, through which air can flow, and an air-permeable cushion cover which spans the cushion surface. At least one electrically driven ventilator blows air into the ventilation layer. In order to optimize efficiency and rapidity of seat ventilation when cooling heated seat surfaces and achieve a compact seat construction without any space demands under the cushion of the seat part and behind the cushion of the backrest, the ventilator is constructed such that it takes air in axially and blows air out at least radially and is arranged in the ventilation layer itself. The intake opening of the ventilator is exposed on the side of the cushion facing away from the cushion cover.
摘要:
A retaining device having an elastic annular collar as a retainer for mounting a vibrating part to obtain, in a constructionally simple manner, good outward encapsulation, for fitting it into a soft part. The retaining device is a retaining ring which surrounds the vibrating part at a radial distance and has longitudinal slots which are distributed around the circumference and run in the circumferential direction. Pins are provided adjacent to and perpendicular to the slots, on which the elastic annular collar is mounted, such that the elastic annular collar does not come into contact with the retaining ring.
