A seat cushion body (1) and method of producing the same are provided. In a method of producing a seat cushion body (1), fiber material is inserted into a mold (21,22). Heat is supplied to the fibers to cause thermal activation of binding fibers, so as to effect thermal cross-linking. The resulting seat cushion body (1) includes a resilient portion (5) formed from the fibers and having a fiber orientation along a main load direction (2) of the seat cushion body (1). The seat cushion body may include at least one further portion (6,7) formed from the fibers, which has a fiber orientation and/or a density different from the fiber orientation and/or different from a density of the resilient portion (5). The resilient portion (5) and the at least one further portion (6,7) may be integrally formed from the cross-linked fiber material as a unitary body.

The invention relates to a regulating device which is used to regulate a lateral part of a seat. Said device comprises a flexible element (31) which is to be coupled to the lateral part, and wherein the arch thereof can be altered in a reversible manner, and a maintaining element which comprises a base section (36) and a pivotable pivoting section (37) which is arranged therein. Said regulating device is embodied in such a manner that the flexible element (31) is initially displaced in relation to the maintaining element and subsequently curved such that a section (34), which is to be coupled to the lateral part, is displaced is an initially linear manner and subsequently arched and which is transmitted to a lateral part of the seat when a force is exerted by means of an actuation device (21, 22).

The invention relates to a multi-way-adjusting device, in particular to a two-way device for a seating component, mainly for adjusting the width of a seatback. The inventive multi-way adjusting device comprises an adjusting element (7) which is movable with respect to a fixing element (1) and requires less energy for adjusting in a first direction (a) than in a second direction (B). In order to compensate said difference, mechanical energy storage elements (5) absorb mechanical energy during adjusting in the first direction (A) and release said energy during adjusting in the second direction (B), thereby facilitating the displacement of the adjusting element (7) in the second direction (B). Said invention also relates to a corresponding adjusting device for a cable control, in particular to a Bowden cable which is used for adjusting the height or the curve of the lordosis support of the seat.

Disclosed is a lordosis support for a backrest of a seat, comprising a lordosis support cage (10) that extends along the longitudinal direction of the backrest, a frame (12) on which the lordosis support cage (10) is mounted, and an adjusting mechanism (11) that modifies the position of the lordosis support cage relative to the frame. The adjusting mechanism is provided with several adjusting members (60), some of which can be moved relative to each other.
摘要:
Es wird eine Verstellvorrichtung für eine Bowdenzuganordnung in Form eines Hand- oder Spannschlosses beschrieben, welche ein Gehäuse (10), eine in dem Gehäuse (10) drehfest und axial beweglich geführte Gewindespindel (70), die mit einem Draht der Bowdenzuganordnung zu koppeln ist, und zwei Halbschalen (50), welche in dem Gehäuse (10) axialfest und drehbar angeordnet sind und sich mit der Gewindespindel (70) in Gewindeeingriff befinden, umfasst. An dem Gehäuse (10) befindet sich ein Ansatz (16) mit einer Öffnung (13), durch welche der Draht der Bowdenzuganordnung in axialer Richtung aus der Verstellvorrichtung geführt ist. Dem Ansatz (16) ist eine Hülse (30) zugeordnet, welche auf den Ansatz (16) formschlüssig aufzusetzen ist und eine Deformation des Ansatzes (16) bei einer Betätigung der Verstellvorrichtung verhindert.

The invention relates to a brake drive comprising at least one brake drum (1), said brake drum being largely prevented from turning, with at least one spreader ring (2) which is situated in the interior space thereof and which has a larger diameter before installation. After installation, the spreader ring (2) exhibits a first inherent expansion friction against turning by means of the expansion force thereof exerted on all points of the friction surfaces (5). Said expansion friction undergoes yet another spreading and braking intensification up to an eventual total locking when a reverse torque occurs on the drive shaft (3) via the driving pin (4) thereof and via the circular pushing force of said pin exerted on one of both faces of the spreader ring (2). The total locking contracts the spreader ring again by turning the primary handwheel (6) or primary despreading pivoted lever (6a) on the input side with the assistance of both despreading pins (6' and 6 ), said pins being fixably mounted on the same, by means of a circular pulling force exerted on the opposite face of the spreader ring. The brake friction or outright blockage is lifted again and it is once again possible to adjust and to fix the entire brake drive in both directions of rotation on the input and output sides at any time.

The invention relates to a lordosis support which is disposed in a backrest frame of a seat. Said lordosis support comprises a lordosis supporting cage (12) which is arranged in a backrest frame (10) of the seat as well as a pulling device that modifies the position of the lordosis supporting cage (12) relative to the frame. The inventive lordosis support is characterized in that the pulling device is provided with two traction cables (16, 17) which are coupled to the lordosis supporting cage (12) and the frame in such a way that the lordosis supporting frame (12) is moved relative to the plane defined by the backrest frame (10) of the seat when the pulling device is pulled.
