摘要:
A passenger seat, an aircraft passenger seat in particular, has seat components such as a seat frame (20), a backrest (12), and a seat cushion carrier (30) with seat cushion (16). The seat depth between backrest (12) and a seat front edge (26) can be varied by an adjustment mechanism (32) with an energy accumulator, such that the seat depth is adjustable and fastenable in desired adjustment positions. The adjustment mechanism has at least one variable-volume energy accumulator. An adjustment position of the seat depth may be associated with each volume level. The seat depth adjustment may be effected essentially free of mechanical components such as sets of levers.

A method is described for forming an aluminosilicate-zeolite layer on an aluminum-containing substrate by in situ direct crystallization. Aluminum-rich aluminosilicate-zeolite coatings on aluminum-containing metal substrates obtained by this method are advantageous, for example, in sorption-based fields of application, such as heterogeneous catalysis, in separation and cleaning processes, in sorption heat pumps, in conjunction with immobilized catalysts and in microreaction technology.

In a disc brake with automatic adjusting device, a nut (12) is screwed to an axially slidable, unrotatable spindle (11). Nut (12) is connected to a coupling element (13). An auxiliary piston (32) is slidably mounted in a bore (31) of the brake piston (4) and is connected to the nut (12) by an axially lockable snap-in connection (35, 37, 38).

A method and apparatus for controlling the braking pressure in an anti-lock brake system which includes a brake power booster operable by an electric control element, wherein the rotational speed of the individual vehicle wheels is determined, the actual rotational speed value measured on a wheel during braking is compared with a memorized desired rotational speed nominal value. The electric control element is actuated as a function of the comparison result.

A hydraulic automotive vehicle brake system with an actuating assembly that is attached to the splashboard of the automotive vehicle and is operable by the vehicle brake pedal. In order to reduce the possibility of risk to the driver during a collision (especially a rear end collision), the present invention provides a system which simulates an increase volume requirement of the brake system, thus permitting increased actuating travel of the actuating assembly.

A multi-part brake disk consists of a friction ring and a bowl-shaped holding part formed from sheet metal and connected in a form-fitting manner to the friction ring by plastic deformation. To ensure an especially simple and inexpensive connection, the holding part is provided with stamped tabs that are distributed over its circumference and project radially outward out of the peripheral face and can be shaped in the holding part by a simple stamping operation directed radially outward.

A longitudinally adjustable column for chairs, tables or the like comprises an upright tube and a length-adjusting element arranged in the upright tube. For fastening to a pedestal a sleeve-like cone section is provided, which is provided on its internal side with at least one recess, with which engages a projection. Over the length of the upright tube several of such projections are provided at a distance from each other, so that the cone section formed by half shells or being simply slotted can be fixed in different height positions on the upright tube in the direction of the axis.

In order to be able to adjust the distance between a reaction disc and a second part of a a two-part valve piston interacting with the former in a completely assembled vacuum brake power booster, a tubular sleeve is provided according to the invention which is disposed coaxially with a piston rod actuating the valve piston, which is axially slidable and which is engageable with a first part of said valve piston being coupled to the second part by means of a threaded union in order to apply a torque to the first piston part.

In order to enable a brake booster to operate both with a pressure above atmospheric and with atmospheric pressure without any negative mutual influences of the two energy types and without any change in the responding behavior of the device in case of failure of either energy type, the invention provides a pneumatic system which, during the operation of the brake booster with pressure above atmospheric, causes a force constituent to become active so as to counteract the forces caused by the increased pressure difference and acting on the control valve piston as well as on the control valve housing.
