The method involves subjecting a mass (2) to oscillations and being of certain part (3), where the acceleration of the oscillations is measured over an acceleration sensor (5). The relative movement is measured over a local sensor (7) as well as a pneumati...

The folding bed (10) has a first segment (12) whose two side edges form right angles with the rear edge, as well as a rectangular segment (11) with each segment forming bed surfaces. Two adjoining segments are connected together along an axis for fixing in...

The leaf spring is for suspension of an upper plate (6) relative to a lower plate (7). It has a spring constant adjusting device (20) with two slides, which are positioned on either side of fastener bolts (16.1,16.2) for the spring and are moveable relativ...

The armrest has a main body (2), a locking part (3) on the seat, and a locking element (4), with all parts positioned concentric about a shaft (6) mounted on the seat. Main body and locking part each have a friction unit (7,8), and these are in contact in ...
