An air supply device for an automotive seat includes an air duct which is arranged at the delivery side of a fan and has at least one air outlet opening provided in the upper region of the seat for supplying the head, shoulder and neck region of a seat occupant with a flow of air. A heating element is arranged in the air duct between the fan and the air outlet opening, and the air supply device has at least one sensor for detecting a parameter value as a function of which the flow of air emerging from the air outlet opening is controlled. In order to provide the air supply device with a flow of air which can be controlled in a more universal manner, the sensor is arranged inside the air duct between the air outlet opening and the heating element.

Air supply device for an automotive seat

A motor vehicle seat having an air supply device by means of which an air flow can be established through a ventilation layer of the cushion of the seat in order to ventilate the seat and/or in order to heat the seat. An air outflow opening of the air supply device is arranged in the upper region of the seat and via which the head, shoulder and neck region of the seat occupant can be acted upon by an air flow. The air supply device is assigned a fan. In order to provide a motor vehicle seat with an air supply device which can be used more universally, the fan can be supplied with air from the ventilation layer of the cushion of the seat in order to generate the air flow for the head, shoulder and neck region of the seat occupant.

Motor vehicle seat having an air supply device

An air supply device for a vehicle seat has an air channel arranged on the pressure side of a blower. The channel comprises at least one air discharge opening provided in the upper region of the seat for supplying the head, shoulder and neck area of an occupant of the seat with an adjustable airflow. A heating element is arranged in the air channel between the blower and the air discharge opening. In order to provide the air supply device with an airflow which feels more comfortable to the occupant of the seat, a grid element is arranged inside the air channel between the air discharge opening and the heating element. As a result, the airflow emerging from the air discharge opening is homogenized and slowed down, and this slowing-down allows more heat to be transferred to the airflow from the heating element.

Air supply device for a vehicle seat

In order a safety device for a motor vehicle seat having a seat cushion part and a backrest, the backrest having a frame, a backrest cover, which faces rearward as seen in the direction of travel, and padding which faces forward, as seen in the direction of travel, and an airbag module is integrated into the backrest, said airbag module being arranged in that region of the backrest which faces the side wall structure of the motor vehicle in such a manner that an airbag is deployed when there is an impact between a driver and the side wall of the motor vehicle, said safety device ensuring a reliable and reproducible emergence of the airbag, it is proposed to arrange the airbag module to the rear of the backrest frame, when looking from the side wall of the motor vehicle.

Safety device for a motor vehicle seat

An air supply device is provided for a vehicle seat of an open-top motor vehicle having at least one air outflow opening which is provided in the upper region of the vehicle seat and via which an airstream can be applied to the head area, shoulder area and nape area of the sitting vehicle occupant in order to reduce undesired draft phenomenon. The airstream can be regulated by way of a control device. In order to provide improved comfort for the sitting vehicle occupant when driving with the top open, the airstream is adjusted, when the air supply device is switched on, by way of the control device as a function of an automatically sensed external parameter value or of a predefined value selectable by the sitting vehicle occupant, to an assigned basic value, starting from which the further adjustment of the airstream is carried out as a function of an automatically sensed further parameter value.

Air supplying device for vehicle seat with airstream adjustment responsive to motor vehicle velocity

A wind protection device for an open motor vehicle includes a passenger cell that has at least one car seat with a backrest. There is on a level with the top area of the backrest at least one air outflow opening of an air supply system. Thereby, the head, shoulder and neck area of the seat occupant is impinged on with an air stream that can be regulated to avoid an undesired air draft. The air supply system has at least one sensor to measure a parameter value, whereby the air stream, issuing from the air outflow opening, is regulated as a function of the parameter value by way of a regulating unit.

Wind protection device for an open motor vehicle

In a motor vehicle seat for an open motor vehicle, with an air supply device integrated in its backrest and/or head restraint, the device including an air outlet duct having an outlet opening arranged on the front side of the head restraint, for supplying the head, neck and shoulder region of the vehicle occupant with hot air, and an air inlet duct having an inlet opening, with a heating element being assigned to the air supply device. The inlet opening of the air supply device is arranged on the rear side of the backrest or of the head restraint and approximately level with or above a rear end wall edge of the motor vehicle.

Motor vehicle seat

An automobile seat for a convertible motor vehicle has a seat back with an appropriate headrest. At least one air outflow opening of an air supply system is arranged in an upper area of the seat back in order to reduce undesirable drafts. At least one additional air outflow opening of the air supply system is provided in the seat surface facing the seat occupant for seat ventilation and/or seat heating purposes.

Automobile seat

A motor vehicle seat for an open-top motor vehicle has a seat cushion part and a backrest which is provided with a pertaining headrest. In an upper area of the backrest, for reducing undesirable draft phenomena for a seat occupant, at least one air outflow device which has an assigned air outflow nozzle of an air supply device is arranged. The air outflow device is vertically adjustable with respect to the backrest and can be secured in an adjusted vertical position.
