A seat post for a bicycle comprises a post body having a first end shaped to be connected to a bicycle frame, a second end shaped to be connected to a saddle, at least two longitudinal portions meshing with each other and slidable relative to one another along a longitudinal extension, and a fixing apparatus by which the two longitudinal portions can be fixed to one another in a settable relative position, the fixing apparatus being influenced to selectively fix and unfix by a radio signal.

Electronically controlled suspension system, method for controlling a suspension system and computer program

An electronically controlled suspension system for a bicycle includes at least one spring element between first and second parts the bicycle, both parts being movably interconnected. At least one parameter of the spring element is modified. At least one actuator influences the spring element to modify the at least one parameter. An electronic module produces a control signal for the at least one actuator. A control device is influenced by the control signal produced by the electronic module. The control device is connected to at least one of the electronic module and the actuator through a radio signal. A corresponding method controls the suspension system for the bicycle and a computer program executes the method.

A headrest of a motor vehicle seat can be folded down into an inoperative position. The headrest has a headrest body and a headrest bracket which are mechanically connected in such a manner, via a bearing part having a sliding bearing and a pivot bearing that a vertical displacement and a pivoting about a horizontal pivot axis arranged perpendicularly to the longitudinal axis of the vehicle are achievable.

Comfort rest for a rear seat

A device for controlling a fluid volume in shape changing elements of vehicle seats has a sliding valve connectable with a fluid pressure source and with shape changing elements for filling the shape changing elements with fluid and discharging fluid from the shape changing elements, the sliding valve having a housing provided with connecting openings for a corresponding one of the shape changing elements and a control slider movable in the housing relative to the connecting openings, the control slider having at least one control opening cooperating with the connecting openings and at least one connecting passage which opens in the control opening and is loadable with fluid from the fluid pressure source, the control slider being formed as an axial slider which is guided on the housing, the axial slider having an axial displaceably sliding head provided with the at least one control opening and the at least one connecting passage and a slider rod rigidly connected with the slider head for axial displacement of the slider head, and the connecting openings in a sliding direction of the slider head being arranged in a row at a distance one after the other.

Arrangement for controlling a fluid volume in shape changing elements of seats

A process for increasing or reducing the internal pressure of at least one hollow body (HK , HK , HK ) to a specified set internal pressure. The set internal pressure is adjusted so that several pressure-increasing steps or pressure-reducing steps are conducted successively until the internal pressure deviates from the set internal pressure at most by a specified tolerance. Each of these steps brings about a pressure increase or pressure reduction the amount of which is not larger than a specified upper limit. In this way, impairments of comfort owing to the rise in pressure or the reduction in pressure are especially avoided. The actual internal pressure is only measured at the beginning of the process. In one design of the invention, this amount depends upon the volumes of the hollow bodies (HK , HK , HK ) and a supply line (VL) as well as (in the case pressure is increased) from the pressure which a pressure generator generates.
