Definitions

  • the present invention relates to an air supply device for a vehicle seat, in particular a convertible, according to the preamble of patent claim 1.
  • the invention further relates to a method for adjusting an air flow according to the preamble of patent claim 5.
  • a generic air supply device which is integrated in a vehicle seat of a convertible, is known for example from German Utility Model DE 92 474 Ol Ul.
  • this air supply device at least one Vietnameseausströmö réelle is provided in the upper region of the vehicle seat, via which the head, shoulder and neck area of the seat occupant can be acted upon by a defined air flow.
  • Such an air flow is intended to reduce the draft phenomena which are undesirable when driving with an open top, in particular flowing backwards into the open passenger compartment.
  • the air supply device is charged with air, which is collected during driving over intended inflow and conveyed by lines and channels by generating a back pressure or with the aid of a fan to Heilausstr ⁇ mö réelle.
  • an air supply device for a seat a convertible in which an improved comfort for the seat occupants is provided during open driving by the effluent from an air outlet opening air flow by means of a control device in response to automatically or individually adjustable parameter values is adjustable so that the seat occupants feel the outflowing air flow as pleasant.
  • a heating element is provided within the air supply device, which can preheat the air sucked from the environment to a certain temperature.
  • the throughput of the outflowing air ie the strength of the air stream, is set by means of a blower.
  • the core of the invention therefore consists in that the air supply device has at least one Peltier element, which offers a heating surface and a cooling surface, via which the air flow can be conducted as a function of parameter values.
  • a Peltier element is usually a thin plate consisting of two different metal plates, which becomes warmer while supplying energy on one side and at the same time becoming colder on the other side.
  • the Peltier element makes use of the so-called Peltier effect, the one Reversal of the Seebeck effect.
  • the biggest advantages of a Peltier element are its small size, the avoidance of any mechanical parts and the avoidance of carrier media. Therefore, a Peltier element can be easily arranged within an air flow channel.
  • the Peltier element is arranged in an air duct arranged inside the vehicle seat of the air supply device according to the invention.
  • a pivotally mounted air damper is arranged, which is controlled via an actuator.
  • the damper is swiveled depending on the selected parameter values to direct the intake ambient air either over the heating surface or the cooling surface of the Peltier element.
  • Whether the sucked air is conducted over the heating surface or over the cooling surface of the Peltier element depends on parameter values, which are either automatically detected by the system or are freely selectable by the seat occupant as default values.
  • External parameter values which can be detected via corresponding sensors, are, on the one hand, the prevailing ambient temperature and, on the other hand, the prevailing driving speed with the accompanying air backflows.
  • Individually adjustable default values from which the further adjustment of the air flow can be made as a function of automatically detectable further parameter values, are for the seat occupant, for example, a desired minimum or maximum temperature for the air flow and a desired minimum or maximum level of airflow.
  • the air strength is regulated and the temperature of the air flow is adjusted, the system then directing the ambient air either over the heating surface or over the cooling surface of the Peltier element.
  • a method for adjusting an air flow of such an air supply device for a vehicle seat of a convertible wherein at an outside temperature of less than 25 ° Celsius, the air flow over the heating surface of the Peltier element and at an outside temperature of greater than 30 ° Celsius, the air flow over the cooling surface of the Peltier element is passed.
  • the Peltier element is turned off, so that the temperature of the outflowing air flow coincides with the prevailing outside temperature.
  • the comfort increase for the vehicle occupants can be adjusted by a corresponding regulation of the strength of the airflow as a function of the respectively prevailing vehicle speed and concomitantly the strength of the air backflows in the neck region ,
  • Showing: 1 shows schematically a perspective view of a vehicle seat of a convertible with an integrated air supply device according to the invention.
  • Fig. 2 shows schematically a side view of the vehicle seat with the air supply device.
  • a vehicle seat 1 for convertibles is shown in perspective. Likewise, it would also be possible to use such a seat in a closed vehicle.
  • This vehicle seat 1 consists of a headrest 2 and a backrest 3.
  • an air outlet opening 4 is provided, via which the head, shoulder and neck area of a seated on the vehicle seat 1 occupant (not shown) can be acted upon with an air flow.
  • a fan blower 5 is arranged, which, as can be seen in FIG. 2, draws in ambient air and supplies it via an air duct 6 to the air outlet opening 4 in the headrest 2.
  • Peltier element 7 is arranged in the air duct 6.
  • FIG. 2 shows a side view of the air supply device according to the invention.
  • the Peltier element 7 is arranged within the air channel 6 such that its cooling surface 9 is oriented in the forward direction and its heating surface 10 opposite thereto.
  • the louver of the louver 8 is pivoted such that the sucked by the fan fan 5 ambient air is passed over the heating surface 10 of the Peltier element 7, which preferably takes place at an outside temperature of below 25 ° Celsius.
  • the Peltier element 7 is actuated by a control device 11, which measures the outside temperature via corresponding sensors (not shown here).
  • the control device 11 can be set by the vehicle occupant manually or individually by means of corresponding default values in advance. On the basis of these default values, the control device 11 will then again set the air flow as a function of the respectively prevailing parameters, such as, for example, the outside temperature and the strength of the air backflow.

Abstract

L'invention concerne un dispositif d'alimentation en air conçu pour un siège de véhicule (1), en particulier un siège de cabriolet, et un procédé pour ajuster l'écoulement d'air d'un dispositif d'alimentation en air de ce type. Le dispositif et le procédé selon l'invention sont caractérisés en ce que la température de l'écoulement d'air peut être ajustée en fonction de divers paramètres, au moyen d'un élément Peltier qui est disposé dans un conduit d'air (6) dudit dispositif. A cet effet, l'écoulement d'air est guidé, soit sur une surface de chauffe (10), soit sur une surface de refroidissement (9) de l'élément Peltier (7).
