Abstract: The invention relates to a protective helmet with an outer shell (1) for distributing impact forces, an interior layer (2) accommodated by the outer shell (1) for attenuating impact forces, and a slot (3) for accommodating an electrical device (4), wherein the outer shell (1) has a chin shell area (6) to cover a chin portion of a protective helmet wearer, wherein the outer shell (1) forms a viewing port (8) for the protective helmet wearer to look through. The protective helmet is characterized in that the slot (3) is arranged on the chin shell area (6) in such a way that the accommodated electrical device (4) is arranged between the chin shell area (6) and the interior layer (2), wherein the protective helmet has an interior cover (10) for essentially completely covering the accommodated electrical device (4) in the direction of the viewing port (8).

Abstract: The invention relates to a protective helmet, comprising an outer shell (1) for distributing impact forces and an antenna (2) for transferring a radio signal, which antenna is arranged at least partially inside the outer shell (1). The outer shell (1) consists of a main material in a main region (5). The protective helmet is characterized in that the outer shell (1) consists of a cut-out material in a cut-out region (6), the cut-out material having a lesser damping effect on the radio signal in comparison with the main material. The invention further relates to a method for producing a protective helmet.

Abstract: A height-adjustable headrest for a seat back of an automobile includes support rods that transfix guide areas attached to the seat back frame. The ends of the support rods positioned below the guide areas are connected with a bracket so that they may ratchet, and may be separated from it by pulling upward. At least the end of one the the support rods is locked in its first position by the bracket against extraction upward, and, in a second position, the support rod may be displaced only by means of a tool so that it may be extracted upward.

Abstract: On a vertically adjustable headrest provided on a backrest of a vehicle seat, a perpendicularly extending center part is arranged on a front side. On the two lateral edges of the center part, a supporting part is pivotally connected in each case by way of a film hinge, which supporting parts can be swivelled toward lateral edges of the headrest. A holding bow is provided on each supporting part. A leg spring, which itself is inserted into the headrest, reaches around the holding bow. The holding bow interacts with the leg spring such that, in the event of a vehicle crash, the supporting parts are displaced into the inoperative position by the mere action of the vehicle occupant's head. Furthermore, one control element respectively can also be applied to the end section of the supporting part, by way of which control element, the supporting part is swivelled in a sensor-controlled manner into the inoperative position in the event of a vehicle crash.

Abstract: A pantograph slipper for current collectors. The pantograph includes a center section and laterally, downwardly directed horns. The center section and the horns are fitted with carbon layers which are cemented to a support and to each other and they form a gradual transition between them. A rupture detection device including a pressure channel extending along the center section and the horns is formed in the carbon layers.

Abstract: A force sensor in the integral/monolithic comprises a monolithic block of elastic material which includes a first, second and third plate; a first pair of leaf spring integrally interconnecting the first and second plate, so that the first and second plates can parallely vibrate relative to each other in a first direction; a second pair of leaf springs integrally interconnecting the first and the third plates so that the first and the third plates can parallely vibrate relative to each other in a second direction being at right angles to the first direction; a shaft clearing traverses a bore in the first plate and is affixed to the second plate; the third plate is provided for connection for force receiving; and strain gauges are placed on all the leaf springs to sense separately forces acting in the first and second directions.
