Abstract: A child safety seat for use in a vehicle comprises a seat body having a seat portion and a backrest portion. Guides on the seat body define a strap path for a strap of an adult seat belt which secures the seat body to a vehicle seat. A strap deflecting lever is movable between a first position clear of said strap path and a second position in which the strap is deflected and thus tightened.

Abstract: A child safety seat has a seat body, a support structure, a first releasable coupling for connecting the support structure to a motor vehicle and a second releasable coupling for connecting the seat body to the support structure. The support structure includes an upwardly facing abutment surface positioned above the seat portion of an adult vehicle seat and in front of the backrest portion thereof, when the first coupling is engaged. The second coupling is arranged to hold the seat body in rigid abutment with the abutment surface on the support structure either so that the seat body is facing forwardly in the vehicle or so that the seat body is facing rearwardly in the vehicle.

Abstract: A child safety seat for use in a vehicle, comprising a seat body (10), and two S-shaped coupling arms (36, 38), each of which is pivotally mounted at one end (46, 48) to the seat body (10) below the front thereof and has a front releasable fastener (58, 60) on its other end (54, 56) for attachment to a front anchorage unit located below the front edge of a vehicle seat (18). The coupling arm (36, 38) is so shaped that an intermediate portion (40, 42) thereof is located in front of both ends (46, 48; 54, 56) thereof when the front releasable fastener (58, 60) is engaged with the front anchorage unit, so as to extend round the front edge of the vehicle seat (18).

Abstract: The invention relates to a suspension seat for a vehicle.The vehicle suspension seat has a back rest guided for vertical movement relative to a base part, a seat rest hinged to the back rest and guided for movement such that the body of the seat occupant swings about an axis through his ankles. An armrest is mounted for movement relative to the back rest and seat rest, so as to minimize movement of the seat occupant's arm relative to a steering wheel, by pivotally supporting the armrest about the instantaneous centers of rotation of the armrest relative to two parts of the seat which move pivotally with respect to each other in response to vertical movement of the back rest.

Abstract: Parallel folding armrest assembly for use on a vehicle seat has a rear hollow housing portion with a forward armrest portion pivotally mounted at its forward end for movement between several parallel positions including a low position which can form a seat cushion extension. The housing portion comprises one elongated element of a four-link parallelogram linkage and has a curved upper forward end surface which conceals the linkage and prevents any possibility of finger pinching during adjustment. An actuating lever positioned in the armrest can be manually lifted about a pivot pin to release a locking pawl slidably carried on one of the parallelogram links from engagement with a selected tooth of a curved rack attached interiorly of the aforementioned curved end surface. A single round bar pivotally supports the housing and is adapted to be demountably fixed to the rear short parallelogram link.

Abstract: This invention relates to a vehicle seat of the type in which a seat part is supported and guided for upward and downward movement relative to a base part by a spring suspension.In order to avoid loss of contact between the feet of the seat occupant and control pedals of the vehicle, the suspension includes linkages connecting the seat part to the base part for relative movement such that the seat occupant's ankles remain stationary whereas his knees swing about an axis through his ankles.

Abstract: Fore and aft isolator assembly for a suspended vehicle seat permits the operator to rotate a single control lever in one direction to allow the seat to be moved to any desired fore and aft position and in the opposite direction to lock the seat in that position in either a fixed manner relative to the seat base or in an "isolate" mode where it is free to travel back and forth to a limited degree against resilient elements. The assembly permits the seat to have a very low profile limited only by the clearance required for the suspension structure. It includes an intermediate frame having a series of rack teeth which is positioned between top and bottom frames attached, respectively, to the seat upper and to the suspension. The bottom frame also incorporates a toothed rack. A rotatable adjusting shaft which is rotatably mounted to the top frame slidably supports the intermediate frame and also fixedly supports a first locking pawl which can engage a selected tooth in the rack on the bottom frame.

Abstract: Recliner mechanism for a vehicle seat has a combination cam and bearing member operated by a manual control member positioned at the end of a rotatable support shaft for lifting one toothed locking segment carried by the seatback frame out of contact with another carried by the seat base, thus permitting the seatback to be tilted to any desired angle. Release of the control member in any position of adjustment permits the cooperating toothed locking segments to move together into locking engagement. A seatback return spring biases the seatback forwardly, while a torsion spring biases the control member and cam member toward their locked position. Where desired, a recliner mechanism can be provided for each side of the seatback with the two mechanisms being mounted at the opposite ends of the rotatable support shaft and operated by a single control member.

Abstract: A contact surface on a toothed segment member which controls the recline position of a seat back is abutted by one or the other of a pair of contact surfaces on a stop element to limit the recline angle of the seat back. An off-center threaded opening in the stop element is adapted to receive a bolt passed through a selected one of a plurality of adjacent openings in a bracket on the seat frame. Thus, by turning the stop element over, it is possible to provide a number of discrete stop positions equal to double the number of adjacent openings in the bracket. Cooperating curved surfaces on the bracket and stop element having their center of curvature on the axis of the seat back support shaft assist in installation and ensure that the abutting contact surfaces can fully engage each other at any angle of adjustment.

Abstract: A seat, in particular for a tractor, has a shoulder support mounted at the upper end of a backrest of the seat on a hinge device. The hinge device, when locked, holds the shoulder support in an upright position but, when released, allows the shoulder support to be tilted downwardly to a horizontal position to support an arm and shoulder of the seat occupant when plowing or reversing the tractor.

Abstract: The invention relates to a seat having a movable lumbar support. An arcuate lumbar support is mounted on a back rest frame of the seat by a mechanism which is operable to move the lumbar support forwards or backwards or to tilt the lumbar support as its axis moves vertical to effect a rolling action thereby to raise or lower the level at which it supports a seat occupant. A screwthread in the mechanism is spring-supported to reduce shock applied by the lumbar support.

Abstract: This invention relates to a load-supporting frame.A load-supporting frame has load-supporting means e.g. in the form of filaments stretched across the frame, the filaments being secured at one end to one of the frame sides and at the other end to a variable tensioning device which itself is connected to the opposite frame side. The tensioning device comprises a spinal column of links each secured to one of the filaments and connected at its opposite end to the adjacent frame side by springs. Intermediate the springs is a variable tension coupling comprising a carriage slidable along the flexible column of links, a slider slidable along the frame side, and a screw connection connecting the slider to the carriage and operable to vary the tension in the filaments adjacent thereto. The frame is particularly intended to provide variable-position lumbar support in the back rest of a vehicle seat.

Abstract: A rotary vibration damper comprises one or more vanes secured to a rotor within a housing filled with damper fluid, the vane or vanes cooperating with one or more fixed walls to define complementary fluid-filled chambers within the housing between which fluid will flow as relative vibratory movement occurs between the housing and the vane or vanes. A partition wall movable axially within the housing like a piston is spaced from one end of the vane or vanes to define a restricted path for the flow of damper fluid between complementary chambers. The restriction of the flow path, and hence the vibration damping effect, can be increased or decreased by axial movement of the partition wall.
