Abstract: A longitudinal adjuster for a vehicle seat having at least one pair of rails. The at least one pair of rails may be formed from a first seat rail for connecting to a seat structure, and from a second seat rail for connecting to a vehicle structure. The seat rails of the pair of rails are displaceable in the longitudinal direction relative to each other and mutually engage around each other to form an inner channel. A securing profile, which is fastened to the first seat rail, is arranged in the inner channel. A rack which is fixed relative to the second seat rail is arranged in the inner channel. The securing profile and the rack are normally spaced apart from each other and enter into engagement with each other in a form-fitting manner in reaction to a predetermined action of force.

Abstract: A longitudinal adjuster (10) for a vehicle seat (1) includes at least one rail pair (12), which is formed from a first seat rail (14), for connecting to a seat frame side part (6), and a second seat rail (16), for connecting to a vehicle structure, that slid relative to each other in a longitudinal direction (x) and engage each other and form an inner channel (18). A reinforcing profiled element (22; 122) is fastened to the second seat rail (16) and is arranged in the inner channel (18). The reinforcing profiled element (22; 122) has a connection section (24), which is led out of the inner channel (18) toward a rear and is connectable to a rear end surface (8) of a seat frame side part (6). The vehicle seat with the longitudinal adjuster, has a seat frame side part (6) connected to a first seat rail (4).

Abstract: A longitudinal adjuster (10) for a vehicle seat (1) includes at least one rail pair (12) with a longitudinal direction (x) relatively sliding and engaging first seat rail (14), for connecting to a seat frame side part (6), and a second seat rail (16), for connecting to a vehicle structure. A first clamping element (20), fastened to the first seat rail and a second clamping element (22), fastened to the second seat rail are usually spaced apart from each other and engage with each other, in response to a defined application of force, for example in the event of a crash. The first clamping element has a connection section (24), which can be connected to a surface (8) of a seat frame side part (6) directed toward the rear. The vehicle seat includes the longitudinal adjuster and a seat frame side part, which is connected to a first seat rail.

Abstract: A motor-vehicle seat longitudinal adjuster (10) includes a seat part seat rail (14) and a vehicle structure seat rail (16). The seat rails (14, 16) are slidable relative to each other in a longitudinal direction (x) and engage each other forming an inner channel (18). An anchor (20), fastened to the second seat rail (16), is arranged in the inner channel (18). A reinforcing profiled element (22), fastened to the first seat rail (14), is arranged in the inner channel (18). The reinforcing profiled element (22) and the anchor (20) are spaced apart from each other and engage with each other in response to a defined application of force (a crash). The reinforcing profiled element (22) has a connecting section (24) extending out of the inner channel (18) toward a rear for connection to a rear end surface (8) of a seat frame side part (6).

Abstract: A longitudinal adjuster (10) for a vehicle seat (1), including at least one rail pair which is formed from a first seat rail (12) and a second seat rail (14), the seat rails (12, 14) of the rail pair encompassing one another and being movable relative to one another in the longitudinal direction (x) and being able to be locked to one another via a locking device (16), the locking device (16) having at least one locking element, in particular at least one latching plate (18) which is movable in the vertical direction (z), the longitudinal adjuster (10) having an additional locking means (30) which is normally inoperative and is actuated only in the event of a crash by mass inertia. A vehicle seat (1), in particular a motor vehicle seat, includes a seat part (2) and a longitudinal adjuster (10).

Abstract: An electroacoustic filter has improved low-pass characteristics. The filter includes a first electroacoustic converter, an electroacoustic element and a grid structure between the converter and the element. The grid structure is acoustically active in one frequency range that lies above the acoustically active frequency range of the first electroacoustic converter.

Abstract: A filter working with surface acoustic waves comprises a piezoelectric substrate (SU), a first transducer (IDT1) arranged in the acoustic track coupled to an input, having a first mean finger period (pi) assigned to a center frequency of a pass band of the filter and a second transducer (IDT2) arranged in the acoustic track coupled to an output, having the same first mean finger period (p1), and a reflector arranged between first and second transducer having a second mean finger period (p2) assigned to a stop band frequency different from the center frequency. Further, a new type of very broad bandwidth filters with small insertion loss and high return loss and high rejection are given that use a substrate that can propagate a PSAW and comprises fan shaped transducers.
