Abstract: 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.

Abstract: A vehicle seat provided with an active suspension, comprising: a resiliently mounted vibration-isolating frame (2), a seat mechanism (6a, 6b, 8a, 8b, 10, 13), which can be adjusted by means of at least two actuators (4a, 4b) and is articulated on the vibration-isolating frame (2), at least two acceleration sensors (11, 12), of which the first acceleration sensor is arranged at a spring supporting point in the vicinity of a first joint axis, and the second acceleration sensor is arranged at a spring supporting point in the vicinity of a second joint axis, and at least two final control elements (S1, S2) and power and control electronics (R1, R2, FFC, E, CU) with which the signals of the acceleration sensors are processed and converted into desired adjusting forces (F*1, F*2), which serve as control commands for the final control elements (S1, S2) for operating the actuators (4a,4b), so that the vibration-isolating frame (2) can be adjusted by means of the two actuators (4a, 4b) in two degrees of freedom

Abstract: In a method for adjusting the temperature of a motor vehicle seat, which includes a seat ventilating system and a seat heater, to a predetermined desired value, in which the temperature of the seat is detected in the region of a seat surface by a first temperature sensor and the outside temperature is detected by a second temperature sensor, the seat ventilating system is switched off below a first temperature threshold for the outside temperature, and the seat heater is switched off above a second temperature threshold for the outside temperature. By these measures, an occupant may be provided with a comfortable micro-climate in the seat region for his/her well-being.

Abstract: A method for determining seat comfort includes the steps of measuring pressure distribution over a seat surface using a pressure sensing system, measuring an actual deformation of the seat surface using a deformation sensing system, and computing a value of seat comfort on the basis of the measured actual deformation of the seat surface and the measured pressure distribution of the seat surface. Apparatus for determining seat comfort includes a pressure sensing system for measuring a pressure distribution on a seat surface, a deformation sensory system for measuring an actual deformation of the seat surface, and an evaluation unit for computing seat comfort from the measured pressure distribution and the measured deformation of the seat surface.

Abstract: A motor vehicle seat with a seat back has a seat back support and a head support attached to the seat back support by a connection element. The motor vehicle seat increases vehicle passenger safety despite its simple construction by connecting the head support to the seat back support. In addition, the head support is positioned relative to the seat back support so that, in the event of an accident, a support of the head of the vehicle passenger occurs in a forward deployed position in relation to the upper body, so that a relative movement between the head and the upper body is prevented.

Abstract: 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.

Abstract: A windbreak device is provided for an open motor vehicle, in whose passenger cell at least one vehicle seat having a backrest and associated head restraint is arranged. Air outflow openings of the air-distributing device are provided level with an upper region of the backrest in order to avoid undesirable draughts for the vehicle occupant. The air-distributing device is integrated in the backrest and is supported directly by the latter.

Abstract: 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.

Abstract: 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.

Abstract: A head restraint for a vehicle seat has a holding element which can be inserted into a seat backrest in a manner allowing it to be displaced vertically. A padding support is arranged on the holding element which holds a padded headrest intended for supporting the head. A pivoting device is arranged between the holding element and padding support and is intended for setting the inclination of the padded headrest about a rotational axis orientated transversely to the seat depth. In order to provide a head restraint which is anatomically shaped and can be set in height and inclination in such a manner that in every position it forms a continuation of the contour of the seat occupant's back, the padded headrest has a padded tongue which is pulled out downwards over the padding support for the purpose of supporting the back of the neck. The contour of the front surface of the padded headrest and padded tongue reproduces the profile of the back of the head and back of the neck.

Abstract: A backrest for a vehicle seat, having a head restraint and backrest padding, and having a supporting element which is intended for the seat occupant's back and, is compliant, at least in the upper backrest region, in such a manner that the seat occupant's back is able to shift rearwards relative to the head restraint in the event of a rear-end collision of the vehicle. The supporting element is formed by a shaped cushion that is integrated in the backrest padding in the upper backrest region, and filled with a gaseous medium, in particular air. In the event of a collision this supporting element can suddenly be deflated.

Abstract: A head restraint for a vehicle seat which has a seat back or backrest, having a head cushion and a retaining device. The retaining device secures the head cushion pivotably to the backrest. The retaining device is designed such that the head cushion can be pivoted between an upper functional position and a lower-lying rest or non-functional position. For the purpose of simplifying the retaining device in terms of design and manufacture, the head cushion and retaining device are connected to each other via a pivot which is aligned transversely with respect to the backrest front surface and passes eccentrically through the plane of symmetry of the head cushion.

Abstract: A vehicle seat with a contour adjustment mechanism and control for the lordosis region of the seatback portion including at least two air cushions arranged one above another, the control including an operating unit and switching assembly for changing air pressure in the two air cushions. Specifically, two sets of operative switches are provided, one set to signal the operating unit to produce a change of the air pressure ratio between the two air cushions and the other set to simultaneously change the air pressure in the two cushions without changing the current pressure ratio.
