Abstract: A device for sequentially switching at least one first and at least one second Venetian blind, the slats of which can each be synchronously rotationally moved by means of at least one coupling rod in order to open and close the blinds. The device includes an actuator for generating a rotational movement of the slats through 80° to 90°, a coupling for rotatably coupling the actuator to a slat of the first blind, a link rod which has a partially-circular link, and a transmission rod. The actuator has an eccentric pin parallel to its axis of rotation which engages in the partially-circular link of the link rod, and the linear movement of the link rod is transmitted to the coupling rod of the at least second blind.

Abstract: An air guidance control unit having a frame, which surrounds at least one air opening for air flowing along an air flow direction to flow through, a closing device including adjustable flaps, which closing device can be adjusted by means of an adjusting element between an open position in which the air opening is exposed and a closed position in which the air opening is at least partly closed. The invention devises various solutions for especially compact and reliable flap arrangements.

Abstract: Air flow control insertable into an air opening for controlling air flowing along an air flow direction, with a closure device including a cloth or fabric adjustable between an opening position releasing the air opening and a closing position at least partially closing the air opening by means of an adjustment device for selectively releasing and closing the air opening to change the air resistance and/or for thermal management of a downstream unit in the air flow direction. Various solutions are proposed to integrate the air control system in or behind an air grille, especially in very limited installation space.

Abstract: This protective device (100) is used in a motor vehicle having a front hood (300), which covers the front of the vehicle, leads up to the front windshield and which, at the windshield, is rotatably coupled via a hinge system (200) to the body of the front of the vehicle on both sides of the vehicle. According to the state of the art, the inventive protective device consists of a hinge support (2), which is provided for indirectly coupling the hinge system (200) to the vehicle body and which is mounted in a raisable manner on the body of the front of the vehicle. The protective device also consists of an energy-storing implement, which acts upon the hinge support (2) while being provided in the form of a spring storage system (4), and consists of a sensor-controlled retaining device (11) for actively engaging with the hinge support (2) so that, in the normal state, the hinge support is held down and during a collision, can be released by sensor actuation in order to execute a limited raising movement.

Abstract: A string tracking apparatus for archery arrows including an arrow having a hollow tubular shaft with a point attached to one end of the shaft. A nock is attached to the other end of the shaft and fletching is disposed near the nock for stabilizing the arrow in flight. A coil of flexible line is disposed within the hollow shaft. A hook-shaped catching structure is attached to the other end of the flexible line. The hook-shaped catching device is frictionally disposed around the front end of the shaft or around the front end of the point attached to the shaft.
