Abstract
Description
- This invention relates to a vehicle seat for a motor vehicle.
- In a known vehicle seat for an open motor vehicle or convertible (see German document DE 100 47 754 A1), to avoid an undesirable draft for the seat user, air discharge openings are provided level with the upper region of the backrest, which air discharge openings are connected to an air-distributing device integrated in the backrest. The air-distributing device has a fan and a heating element for heating the air flow. Of the air discharge openings, one is arranged in the upper side of the backrest and two are arranged in the lateral narrow sides of the backrest. The air discharge openings are oriented in such a manner that the air flow is discharged essentially in the transverse direction of the vehicle. To avoid eddies of cold air when traveling with the motor vehicle open, a wind deflector is integrated in the backrest, is designed, for example, as a roller blind, and can be extended out of the backrest or retracted into the backrest manually or by motor. In the extended position, the upper edge of the wind deflector is fixed to the rear side of the head cushion. In this case, the wind deflector extends over the entire width of the backrest and tapers toward the head cushion.
- In another vehicle seat which is likewise known (see German document DE 101 60 799 A1) and which has an additional heating system for the head, neck and shoulder region of the seat user by means of hot air being blown out, a pressure connection of a hot air fan ends with its blow-out opening in the intermediate space between the head cushion and the upper side of the backrest. The normal of the blow-out opening of the pressure connection is oriented approximately horizontally, so that the head, neck and shoulder region of the seat user has hot air flowing directly against it.
- One object of the invention is the object of more effectively designing the ventilation device for supplying hot air to the head, neck and shoulder region of the seat user so that, while any flow noises are negligible, the seat user experiences a comfortable sensation of heat without there being any draft.
- This object is achieved according to the invention.
- The vehicle seat according to the invention has the advantage that, by means of a diffuser present in the intermediate space between backrest and head cushion, the hot air blow-out opening, which is enclosed in the upper side of the backrest and is advantageously not directly visible, does not issue a directed and focused hot air stream which directly impacts against the neck and head and shoulder region of the seat user or flows past that region at a great flow rate. Rather, the opening issues a diffuse, fanned-out, gentle hot air flow which acts upon the neck and head region of the seat user and, as a result, in this region forms a type of hot air cushion which initiates a comfortable sensation of heat for the seat user. Owing to the fact that the diffuser covers the intermediate space between backrest and head cushion to the rear, the formation of the hot air cushion cannot be disturbed from the rear by horizontal air flows. By the length-variable diffuser being fixed to the head cushion and to the upper side of the backrest, this hot air cushion is produced and maintained irrespective of the size of the seat user and the head restraint height setting, which is dependent on seat user size. Advantageous embodiments of the vehicle seat according to the invention together with expedient developments and refinements of the invention are defined by the further patent claims.
- According to a preferred embodiment of the invention, in the transverse direction of the seat, the diffuser covers the region between the two supporting rods of the head restraint. This affords the advantage that the view of the seat user, in particular of the driver, to the rear is not restricted, without compromises having to be made with regard to the hot air cushion produced in the head, neck and shoulder region of the seat user.
- The invention is described in more detail below with reference to exemplary embodiments illustrated in the drawings.
-
FIG. 1 shows part of a side view of a vehicle seat, occupied by a seat user, with backrest, head restraint and hot-air ventilation device, -
FIG. 2 shows part of a front view of the backrest with the head restraint inFIG. 1 without the seat user, -
FIG. 3 shows an identical illustration as inFIG. 1 with a modified diffuser of the hot-air ventilation device, -
FIG. 4 shows an identical illustration as inFIG. 1 with a diffuser according to a further exemplary embodiment, -
FIG. 5 shows a section along the line V-V inFIG. 4 , -
FIG. 6 shows part of a front view of the backrest of a vehicle seat with a hot-air ventilation device according to a further exemplary embodiment, and -
FIG. 7 shows a side view of the backrest with the hot-air ventilation device according toFIG. 6 with a modified diffuser. - The vehicle seat, part of which is illustrated in side view in
FIG. 1 and in plan view inFIG. 2 , has abackrest 11, a height-adjustable head restraint 12 and aventilation device 13 which is integrated in thebackrest 11 and by means of which the head and neck region and also partially the shoulder region of aseat user 10 sitting on the vehicle seat is acted upon with hot air. Thehead restraint 12 has in a known manner a U-shaped supportinghoop 14 with two parallel supportingrods 141 to the transverse part of which, which connects the two supportingrods 141, ahead cushion 15 is fastened. The supportingrods 141 are guided in a known manner in thebackrest 11 such that they can be displaced axially, so that thehead restraint 12 can be set in its setting height, i.e. the distance of itshead cushion 15 from theupper side 111 of thebackrest 11, in accordance with the size of theseat user 10. - In order to blow out the hot air of the
ventilation device 13, a blow-outopening 16 is embedded in theupper side 111 of thebackrest 11 and is the mouth opening of apressure connection 17 of asuction fan 18 of theventilation device 13, which suction fan is integrated in thebackrest 11. In a manner not illustrated further, thesuction fan 18 sucks up hot air and blows it out via thepressure connection 17 and the blow-out opening 16. Alternatively, thesuction fan 18 can suck up ambient air from the interior of the vehicle, with the air being guided over an electric heating element. The discharge direction of the hot air from the blow-outopening 16 is directed toward thehead cushion 15. - In order to achieve an effective circulation of hot air around the head, neck and shoulder region of the
seat user 10, adiffuser 19 is arranged in the intermediate space between theupper side 111 of thebackrest 11 and thelower side 151 of thehead cushion 15 in such a manner that it covers the intermediate space to the rear from an airflow. In the transverse direction of the seat, thediffuser 19 here fills the region between the two supportingrods 141 of the supportinghoop 14 of thehead restraint 12. Thediffuser 19 is designed in such a manner and oriented relative to the blow-outopening 16 in theupper side 111 of thebackrest 11 in such a manner that it alters the focused hot air stream, which emerges from the blow-outopening 16 and is directed toward thehead cushion 15, into a wide, diffuse hot air flow with a low flow rate aiming at the neck and head region of theseat user 10. In the exemplary embodiment ofFIGS. 1 and 2 , thediffuser 19 is formed by astretched cloth 20 which is inclined at an acute angle to theupper side 111 of thebackrest 11 and extends from the rear edge of theupper side 111 of thebackrest 11 as far as the front edge of thelower side 151 of thehead cushion 15. Thecloth 20 is pulled off in the manner of a roller blind from a reel of cloth wound up on a pretensioned, resetting roller-blind-type rod 21. When thehead restraint 12 is adjusted in height, thecloth 20 is pulled off from the reel of cloth to a greater or lesser extent and always remains tensioned tautly approximately in the inclination, shown inFIG. 1 , with respect to the blow-out opening 16 in theupper side 111 of thebackrest 11. InFIG. 1 ,air flow arrows 22 symbolize the manner in which the hot air stream being discharged from the blow-out opening 16 in the direction of thehead cushion 15 is altered by thecloth 20 into a wide, diffuse hot air flow directed at the neck andhead region 12 of theseat user 10. - In the case of the vehicle seat which is partially illustrated in
FIG. 3 and is occupied by aseat user 10, thediffuser 19 is designed as apleated cloth 23 which can be expanded in the manner of a concertina and, like thecloth 20 inFIGS. 1 and 2 , is fastened to the rear edge of theupper side 111 of thebackrest 11 and to the front edge of thelower side 151 of thehead cushion 15, with the folds of thepleated cloth 23 running in the transverse direction of the seat. Thepleated cloth 23, which, as a result, is likewise inclined toward theupper side 111 of thebackrest 11, again extends in the transverse direction of the seat between the supportingrods 141 of the supportinghoops 14 of thehead restraint 12. A height adjustment of thehead restraint 12 is compensated for by a reduction or an enlargement of the height of the folds in thepleated cloth 23, so that thepleated cloth 23 always remains tensioned. - In the exemplary embodiment, illustrated in
FIG. 4 , of the vehicle seat, thediffuser 19 is formed by anexpansion bellows 24 which surrounds the two supportingrods 26 and is fastened on theupper side 111 of thebackrest 11 and to thelower side 151 of thehead cushion 15. As the sectional illustration inFIG. 5 shows, theexpansion bellows 24 is open continuously longitudinally in its front region pointing to the neck and rear of the head of theseat user 10, so that the hot air flowing out of the blow-out opening 16 into theexpansion bellows 24, after being deflected and scattered against the walls of the expansion bellows, emerges from theexpansion bellows 24 in a diffuse manner on the front side of theexpansion bellows 24, which side is directed toward theseat user 10. - In the case of the exemplary embodiment of the vehicle seat in
FIG. 6 , thediffuser 19 is formed by a blow-outduct 25 which surrounds the blow-out opening 16, enters thebackrest 11 and can be displaced axially there in the manner of a telescope on thepressure connection 17 of thesuction fan 18 of theventilation device 13. The blow-outduct 25 is fastened to thelower side 151 of thehead cushion 15, so that it is carried along during a height adjustment of thehead restraint 12 and is displaced on thepressure connection 17 of thesuction fan 18. Theduct section 251 of the blow-outduct 25, which duct section extends between theupper side 111 of thebackrest 11 and thelower side 151 of thehead cushion 15, covers, in the transverse direction of the seat, the intermediate space between the two supportingrods 141 of the head restraint 12 to the rear and is open on its front side pointing to the neck and head region of theseat user 10, so that the hot air again acts in the desired manner upon the neck and head region of theseat user 10. - In the exemplary embodiment illustrated in
FIG. 7 , theduct section 251 of the blow-outduct 25 is additionally curved forward, thus assisting the deflection of the hot air flow. In addition, it is indicated by chain-dotted lines that this embodiment of the ventilation device is suitable with adiffuser 19, designed as a blow-outduct 25, forbackrests 11 with an integratedhead restraint 12, in which anend portion 26 of the backrest is pulled up behind the height-adjustable head restraint 12.
