The invention relates to a vehicle seat comprising at least one gas spring (9) which damps vibration and adjusts the seat height, said gas spring being arranged between a seat frame (1) and a base frame (2), and comprising a valve arrangement (43, 44) for adjusting the pressure in the gas spring (9) and a compressor (45) assigned to the vehicle seat (17, 20, 23), said compressor having a drive motor for feeding compressed gas to the gas spring (9), wherein a belt roller device comprising a belt (11) rolled around an axle (12) is arranged between the seat frame (1) and the base frame (2), the first end (11a) of said belt being attached to a belt roller mechanism (10) arranged on the seat frame (1) and the second end (11b) of said belt being attached to the base frame (2), and a detector (16) which detects a belt rolling movement is attached to the seat frame (1). Use is made of an electronic control unit (14, 38, 40) for evaluating belt rolling movement signals detected within a predefined time period (26, 27, 29) for determining a seat height profile within the time period (26, 27, 29) and for controlling the valve arrangement (43, 44) and/or the compressor (45) such that automatic, time-delayed seat height re-adjustment takes place if the seat height profile (31, 35) determined for the time period (26, 27, 29) lies out of a position of symmetry in relation to a predefinable mean seat height (28). Also disclosed is a method for carrying out such automatic seat height adjustment.
摘要:
A vehicle seat which is adjustable in height and which affords automatic adjustment to the seat occupant weight comprises a gas spring between a seat frame and a base frame, a valve arrangement actuable by an actuating element to adjust the pressure in the gas spring in dependence on the weight of the seat occupant, and a means for setting the desired seat height. Disposed between the seat and base frames is a belt reel device with a coupling means, which like the gas spring, can be subjected to the action of pressure gas from a pressure source. The pressure source comprises a compressor driven by a drive motor, which are disposed on the vehicle seat. The valve arrangement includes a 2/2-way valve which serves only for the release of pressure gas from the gas spring, and a 3/2-way valve between the pressure source and the coupling means of the belt reel device. The valve arrangement may be mechanical/pneumatic in operation or may be controlled by an electronic control arrangement.

The device (10) comprises a deposition chamber (12) containing two electrodes (13, 14), one of which comprises a support (16) for a substrate (17) and is earthed, the other being connected to an electric radio frequency generator (15). The device includes a mechanism (23) for extracting gas from the chamber (12) and a mechanism (18) for supplying gas. The device also comprises a mechanism for purification (31) of the gases introduced into the chamber, these a mechanism being arranged so as to reduce the number of oxygen atoms contained in the deposition gas, such gas being made up of silane, hydrogen and/or argon. The procedure consists of creating a vacuum in the deposition chamber (12), purifying the gases using purification a mechanism (31), introducing these purified gases into the chamber (12), then creating a plasma between the electrodes (13, 14). A film of intrinsic microcrystalline silicon in then deposited on the substrate.

The invention relates to an ultrasonic transducer with a pot-shaped oscillating element, which is mounted in a transducer housing and which bears a piezoelectric disc on its bottom. The invention simplifies the electric contact-making between the connecting leads and the oscillating element or the piezoelectric disc and makes this process more suitable for automated manufacturing. The invention consists of contact springs which are not soldered or caulked with the above-mentioned elements, but only tact them resiliently. Improvements are achieved through an essentially cylinder-shaped connecting element, to which the contact springs are fastened by casting and which can also serve as a damping element.

A guide rail arrangement for a vehicle seat has first and second rail members. The first and second rail members are of configurations which engage one into the other to hold the rail members slidably together and they have first and second contact portions, along which the rail members bear linearly against each other for mutual play-free guidance thereof.
