Definitions
- the invention relates to a vehicle seat according to the preamble of claim 1.
- a known vehicle seat (DE 10 63 049 AI, DE 101 63 050 AI, DE 101 63 051 AI) there is an air duct in the head cushion of the headrest with an air inlet opening arranged on the rear side of the head cushion facing away from a seat user and one on the side facing the seat user Warm air outlet opening arranged on the front is formed.
- the warm air device is integrated in the air duct and comprises an electric heating element and an axial fan, which are arranged one behind the other in the air duct.
- the air sucked in by the axial fan via the air inlet opening on the back of the head cushion is passed through the heating element, and the warm air is blown out of the warm air outlet opening directly into the neck and head area of the seat user, with more of the neck and Shoulder area or more the neck and head area of the seated person is directly exposed to warm air.
- the invention has for its object to improve the warm air heating of the neck and head area of a seat user so that the comfort of seat users of different body sizes is improved.
- the object is achieved by the features of claim 1.
- the vehicle seat according to the invention has the advantage that the arrangement of the warm air outlet opening on the underside of the head cushion and the partitioning of the space between the head cushion and backrest to the rear does not directly blow the back of the seat with warm air, but rather a heat cushion in the neck and head area of the seat user is built up, which also extends over the shoulder area.
- a heat cushion gives the seat user a much greater feeling of warmth than is achieved with direct warm air radiation, since there are no noticeable air currents or temperature fluctuations in the heat cushion.
- This heat cushion is retained even when the headrest is adjustable in height, which is adjusted according to the body size of a seat user, since the heat cushion is always built up in the space between the head cushion and backrest and this is always sealed off regardless of the adjustment of the head cushion to the rear.
- an air guiding element is arranged in the space between the head cushion and backrest, which is designed such that the warm air flowing out of the warm air outlet opening is deflected towards the neck and head area of the seated person.
- the air guide element can be formed separately and attached to the top of the backrest, but can also be made in one piece with the cover.
- FIG. 1 is a partial side view of the backrest and headrest of a vehicle seat with a headrest shown in section and an integrated warm air device
- FIG. 2 is a partial perspective view of the backrest and headrest in the direction of arrow II in Fig. 1,
- FIG. 3 shows a detail of a rear view of the backrest and headrest with a warm air device according to a further exemplary embodiment
- FIG. 4 shows a partial side view of a vehicle seat with a backrest occupied by a seat user and a headrest with a warm air device according to a third exemplary embodiment, shown in longitudinal section,
- FIG. 5 is a side view of the backrest and partially cut headrest with integrated warm air device of a vehicle seat, according to a fourth embodiment
- FIG. 6 shows a section along the line VI-VI in FIG. 5.
- the vehicle seat shown in detail in FIG. 1 in side view and in perspective rear view in FIG. 2 has, in addition to the seat cushion (not shown here), a backrest 11, a height-adjustable headrest 12 and a device 13 for heating the neck and head area of a seat user 10 (FIG 4) with warm air, hereinafter called hot air device 13 for short.
- the headrest 12 consists in a known manner of a U-shaped support bracket 14 with two parallel support days 141, 142 (FIG. 6) and a head cushion 15 which is attached to a cross part of the support bracket 14 connecting the two support rods 141.
- the support rods 141, 142, of which only the support rod 141 can be seen in FIG. 1, are guided axially displaceably in the backrest 11 in a known manner, so that the adjustment height of the headrest 12, that is the distance of the head cushion 15 from the top 111 the backrest 11 can be changed in accordance with the size of the seat user 10.
- An air duct 16 is formed in the head cushion 15, which has an air inlet opening 17 and a warm air outlet opening 18 arranged on the underside 152 of the head cushion 15 on the rear side 151 of the head cushion 15 facing away from the seat user 10.
- Air inlet opening 15 and warm air outlet opening 18 are each closed with a grille 19 or 20, a so-called rosette.
- the warm air device 13 is integrated in the air duct 16 and comprises an electrical heating element 21, which can be designed, for example, as an electric heating coil, and an axial fan 22, which is preferably designed as a miniature fan.
- the heating element 21 and the axial fan 22 are arranged one behind the other in the air flow direction, wherein the axial fan 22 can be arranged upstream or downstream of the heating element 21.
- the cover 23 thus has a rear wall 231, which seals off the intermediate space to the rear, and two side walls 232 and 233 (FIGS. 1 and 2), which partially cover the intermediate space laterally.
- the rear wall 231 and the two side walls 232, 233 extend from the bottom 152 of the head cushion 15 to the top 11 of the backrest 11.
- the cover 23 is designed differently taking into account the height adjustability of the headrest 12:
- the cover 23 is an elastic curtain which is fixed on the head cushion 15 and on the backrest 11 in the manner described above.
- the elastic curtain is stretched to a greater or lesser extent, so that the space between the head cushion 15 and the upper side 111 of the backrest 11 is always shielded to the rear, in the exemplary embodiment of FIGS. 1 and 2 also partially to the side.
- the gap within that of the cover
- an air guide element 24 is arranged, which is attached to the top 111 of the backrest 11.
- the air guiding element designed here as a wedge
- the cover 23 is designed as an apron 26, which is fastened on the one hand to the underside 152 of the head cushion 15 and, on the other hand, is braced on the back 112 of the backrest 11 by means of two elastic bands 27, 28.
- a cloth or a rigid plate can be used as the apron 26.
- the backrest 11 has a raised backrest extension 29 which is an integral part of the backrest 11.
- the seen in the longitudinal direction of the seat The axial depth of the backrest extension 29 is substantially smaller than the axial depth of the backrest 11.
- the width of the backrest extension 29 seen in the transverse direction of the seat corresponds approximately to the width of the head cushion 15.
- the guide bracket 14 in the backrest 11 is guided in the region of the backrest extension 29 performed.
- the head cushion 15 is designed in such a way that it overlaps the backrest extension 29 on its front facing the seat user 10, in such a way that the overlap is retained even when the headrest height is set to a maximum.
- the space formed between the underside 152 of the head cushion 15 and the upper side 111 of the backrest 11 is covered by the backrest extension 29, which takes over the function of the cover 23 in FIGS. 1-3.
- the headrest 12 with the head cushion 15 and the warm air device 13 integrated therein is otherwise identical to the headrest 12 in FIG. 1, so that the same components are provided with the same reference numerals.
- the head cushion 15 in FIG. 4 is slightly chamfered on its underside 152, so that the normal of the warm air outlet opening 18 lying in this chamfer is set at an acute angle to the vertical and in the direction of the shoulder area of the Seated points. This adjustment of the normals of the warm air outlet opening 18 achieves the same effect as with the air guiding element 24 in FIG. 1.
- the air guiding element 24 ′ for deflecting the warm air flowing out of the warm air outlet opening 18 toward the head, neck and shoulder region of the seat user 10 is not designed as a wedge, as in FIG ,
- the air duct element 24 ′ extends from the top 111 of the rear side 12 through the warm air outlet opening 18 into the air duct 16.
- the vertical length of the air guiding element 24 ' is selected such that the headrest 12 is at maximum height adjustment the air duct element 24 'is still immersed in the air duct 16.
- the air guide element 24 ' is fastened to the top 111 of the backrest 11 by means of two fastening tabs 30, 31 which enclose the support rods 141, 142 of the headrest 12 with play.
- the air guiding element 24 ′ simultaneously takes over the function of the cover 23, the trough bottom forming the rear wall 231 and the trough side walls forming the side walls 232 and 233 of the cover 23.
- the end of the trough-shaped air guide element 24 'projecting into the air guide shaft 16 is open, so that the warm air already partially flows into the air guide element 24' and flows out through the trough opening, as is arranged in FIG. 5 by air guide arrows.
- the other end of the tub opposite the open end of the tub is closed with an end wall that runs obliquely from the tub floor to the tub opening.
- the air guide element 24 ' can be seen in cross section in FIG. 6.
