Abstract: An adjustable safety seat for children for use in a motor vehicle. Height and width configuration of the seat can be easily changed to suit children of different sizes or a growing child.The child's safety seat comprises a pair of side pedestals and a seat bench. Raising of the bench relative to the pedestals for a small child concurrently narrows the width of the seat and lowering of the bench for a larger child concurrently widens the seat.The safety seat and a child contained therein are securely and safely positioned on a vehicle seat by means of the vehicle seat belts.
Abstract: The raising wheel chair substantially comprises the frame (11), wheels (13 and 15) and the seat (17) pivotably connected to the frame (11). A footrest (21) at the front and a backrest (19) at the back are pivotably connected to the seat (17). For raising the user into an upright position, a spring (27) applies a force which acts counter to the weight of the user, so as to facilitate raising the user to an erect position. A support arm (37) which can be arrested in various positions is pivotably connected to the pivot axis on both sides of the frame (11). To arrest the support arm, the locking lever (41) has a multiplicity of locking positions (45), which can be engaged by a locking element (47). The arm (37) can be put into a horizontal position, in which it offers no hindrance to the user in performing a lateral transfer movement, for instance to shift to a toilet seat.
Abstract: A chair is described which comprises a fixed base structure, a seat, an element moveable relative to the fixed structure of the chair, the moveable element being moveable from a first operative position to a second operative position as a result of a thrust exerted by the body of a seated person, and resilient means biasing the moveable element towards its first operative position. The seat of the chair has at least one part moveable substantially vertically (the movement of the moveable element being distinct from the substantially vertical movement of the moveable part of the seat). The chair also includes a resilient member for returning the moveable part of the seat to a raised position for sensing the weight of the seated person, and for adjusting automatically the load of the resilient member in dependence on the weight of the seated person.
Abstract: A utility booster chair including a back and a pair of spaced opposed arm members extending in substantially perpendicular relation therefrom, the chair being contour formed in the shape of an animal and having a platform adjustably connectable to the arm members for different heights and different usages.
Abstract: The width of a laterally foldable wheelchair can be reduced by the chair occupant by manipulation of a hand lever on one side of the chair frame which is operable to elevate a flexible seat support member thereby inducing partial folding of the chair to reduce its width. The weight of the occupant on the chair seat tends to bias the hand lever toward its inactive stowed position.
Abstract: A commerical vehicle seat with a mechanism for adjusting the seat to the weight of the driver, wherein there is provided a support plate for the backrest of the seat capable generally of upright motion relative to a backrest support. Between the backrest support plate and the support backrest there is at least one spring for biasly a seat support bracket, with one end of the spring being able to be moved in relation to the backrest support plate (or the backrest support) by an adjustment member which adjusts to different weights. More specifically, this end of the spring is connected to a support lever which may be rotated about a generally horizontal axis and is fixed to the backrest support, while the other end of the spring is acted upon by an adjustment lever which may be spring-locked in a number of different positions for keeping the support lever in different positions of adjustment. The adjustment lever is also rotatably fixed to the backrest support.
Abstract: A wheelchair capable of being constructed in several different sizes from components of standard size in order to permit users of different sizes and users with one or more handicaps to utilize such wheelchairs. The wheelchair includes a main frame and a foot support assembly which can be telescopically adjustably affixed to the main frame. In addition, a seat section can be telescopically adjustably affixed to the main frame such that the seat is located at a selected height and the foot support section can extend outwardly from the frame for a selected distance to accommodate users of differing height. The rear wheels are positionally mounted with respect to the main frame such that the rear wheels can be located in several different positions in order to change the overall center of gravity and the wheelbase of the wheelchair. In this way, the wheelchair can be used for conventional wheelchair movement, as well as for athletic activities.
Abstract: In association with a foldable chair having retractable back and seat cushions for storage purposes, means are provided for elevating the cushions for use, after the chairs have been unfolded and arranged in rows.
Abstract: A bath seat for babies which includes a seat having at least one hole formed on a central portion of a curved upper surface thereof and groove portions formed at a central portion of opposite sides of the seat, a first and second catch member disposed within the groove portions, a base member disposed beneath the seat, a plurality of supporting plates connected to the base and including idle-holes formed therein, a plurality of support legs connected to the seat and a first and second supporting rod connected to said supporting legs, adjustably positioned within the idle-holes of the supporting plates and connected to end portions of the first and second catch members, respectively, for adjustment of positioning within the idle-holes of the supporting plates and corresponding positioning of said seat.
Abstract: The chair has a hinged seat which can be pivoted into an upright position and a tubular frame with a configuration permitting stacking of chairs when the seats are upright. The upright tubular frame portions have telescoped sections on each side to permit vertical adjustment of the chair. Seat support clamps attached to the outer tube have locking pins for holding the desired vertical position. A pair of telescoped tubes are hinged to each clamp and a seat fixed to the outer ones. The inner tubes of the pairs are connected together parallel to each other by a transverse member. A turnbuckle is connected under the seat between the middle of the cross transverse member and the seat to permit forward and backward adjustment of the seat. Particular features are disclosed for the seat support clamps for making the adjustments easier.
Abstract: An adjustable wooden bench has four legs, the upper portions of which are connected by a pair of horizontal rails provided with vertical openings through which the legs extend. The rails support a seat that is slidable lengthwise of them. A horizontal footrest rail like the top rails is mounted on the lower portions of the front legs. The top front rail is supported by a pair of flexible cables anchored at one end to the front legs above the rail, with the cable extending down through the rail and then lengthwise of the rail in opposite directions in engagement with its bottom and then down to anchors on the other front legs. Normally, the cables are locked against movement lengthwise of the rail to prevent it from moving vertically. The back rail and the footrest may be supported by cables in the same way as the front rails.
Abstract: An adjustable chair includes a pair of upwardly extending spaced uprights having a plurality of horizontal grooves provided along the substantial length thereof at inner surfaces of the uprights and facing each other, a foot rest plate and a seat bottom plate member having opposite ends respectively disposed in opposite ones of the grooves at desired vertical locations along the uprights. The foot rest and the seat bottom are interchangeable and are tightly held in place by fastening means extending between the uprights.
Abstract: An invalid chair for handicapped persons designed to facilitate sitting down and rising in which the seat of the chair and the footrest are a single frame and both are pivotally mounted to a front cross member so that the seat will be moved pivotally up and forward as the footrest moves down and back to thus assist the person in rising from the chair and vice versa the seat will move pivotally down and back as the footrest moves up and forward and in addition a plurality of resilient springs or stretchable straps will resist the downward movement of the seat to assist the invalid in a seating operation and resist the progressive upward pivotal movement of the chair's footrest.
