(14) In the prior art seat 1 already briefly described above the relatively long tubular part 3 of frame 2, which is covered with backrest 4, and the shorter frame part 5 which carries the console 7 for a steering wheel or the joystick are connected pivotally to each other by means of hinge 8. Known seat 1 is thereby movable between a collapsed position in which seat 1 can be stored (FIG. 3) and a folded-out position of use (FIG. 2). In this seat 1 the console 7 and pedal support 11 also take a pivotable form, respectively by interposing of simple brackets 13 with which console 7 is mounted on sub-frame 16 and by interposing of spacer 12. In the known seat 1 the folded-out position of use is bounded by two straps 10 which are tensioned between frame parts 3, 5 and in the folded-out position form two armrests. The folded-out position of use is determined by adjusting the length of these straps 10.

(15) A seat 101 according to the invention, which is intended for playing video games, comprises a collapsible frame 102 which carries a seat surface 109 and a backrest 104 (FIG. 4). Seat surface 109 and backrest 104 are in this embodiment formed integrally from a flexible material, for instance a fabric. In the shown embodiment frame 102 comprises a number of separate frame parts which are connected to each other with interposing of a hinge 108. A first frame part 103 carries backrest 104, while a second frame part 105 carries a separate sub-frame 116 with thereon a console 107 on which a racing steering wheel 117 is mounted in the shown embodiment. Instead of a steering wheel 117, a joystick could also be mounted on console 107 of sub-frame 116. In order to simplify getting in and out of the seat, sub-frame 116 can be connected to frame part 105 releasably on one side and pivotally on the other side, so that it can be released and folded away to the side.

(16) A forward-directed foot end of frame 102 carries a pivotable spacer 112 with a support 111 for a separate pedal set 118. Steering wheel 117 (or optionally the joystick) and pedal set 118 are connected to a game computer (not shown here). Seat 101 can be placed in front of a screen (not shown here either), after which a user can sit in seat 101 and can control the game using hands and feet via steering wheel 117 (or the joystick) and pedal set 118.

(17) According to an aspect of the present invention, the seat 101 shown in FIG. 4 is distinguished from the known seat 1 of FIGS. 1-3 in that hinge 108 itself can be locked, whereby the frame parts can be fixated relative to each other without having to make use of tensioning straps. This considerably simplifies getting in and out.

(18) Hinge 108 is for this purpose provided with locking means 119. In the shown embodiment the locking means enable the frame parts to be fixated in different positions relative to each other, whereby seat 101 can be adjusted to players with various postures. The locking means can be force-locked, i.e. for instance operate according to the principle of friction, but this requires a (relatively great) force to act on the hinge under all conditions, which requires a heavy construction or requires a continuous supply of energy. In the shown example locking means 119 are therefore form-fitting; they operate according to the principle of mutually engaging parts.

(19) In the shown embodiment hinge 108 comprises two hinge parts 133, 134 which are rotatable relative to each other. Locking means 119 comprise here two locking parts 120, 121, particularly rotatable, which are displaceable relative to each other and are each connected to one of the hinge parts 133, 134. Each locking part 120, 121 is provided with a circularly running toothing 122, 123. Locking parts 120, 121 are movable between a first position shown with full lines in FIG. 7, in which toothings 122, 123 mutually engage and the locking parts 120, 121 are thus blocked, and a second position shown with broken lines (wherein the reference numerals are provided with an accent), in which the toothings 122, 123′ are held at a mutual distance. In the second position the locking parts 120, 121′ and the hinge parts 133, 134′ connected thereto are rotatable relative to each other, whereby the relative position of the frame parts can be varied and reset.

(20) Locking means 119 here comprise a securing member 124 with which locking parts 120, 121 can be secured in their first position, so the locked position in which toothings 122, 123 engage in each other. In the shown embodiment this securing member 124 comprises an eccentric 125. Eccentric 125 forms part of a handle 126 which is pivotable about a shaft 127. This shaft 127 is arranged on a stem 128 which protrudes outward from first locking part 120 through a central opening 129 in second locking part 121. Eccentric 125 has a segment 130 with a relatively small radius R1 and a segment 131 with relatively large radius R2.

(21) When handle 126 is pivoted to a first position, in which it extends substantially parallel to second locking part 121, segment 131 with relatively large radius R2 is in contact with an outer surface 132 of second locking part 121, whereby shaft 127 is situated further from this outer surface 132 and stem 128 is thus pulled into second locking part 121 on the opposite side. Toothings 122, 123 are hereby urged into engagement with each other so that the two locking parts 120, 121 are blocked relative to each other.

(22) When frame 102 has to be placed in a different position, hinge parts 133, 134, and so with this also locking parts 120, 121, have to be rotated to a different relative position. Handle 126 is for this purpose pivoted through about 180° to a second position, in which it extends substantially parallel to second locking part 121 substantially on the other side of shaft 127. In this position of handle 126′ the segment 130′ with relatively small radius R1 is in contact with an outer surface 132′ of second locking part 121′. Shaft 127 is thereby situated closer to this outer surface 132′ and stem 128 can thus extend on the opposite side outside second locking part 121′. A distance D is hereby created between the two locking parts 120, 121′, whereby the toothings 122, 123′ disengage and locking parts 120, 121′ can be displaced, for instance rotated, relative to each other. In order to urge the locking parts 120, 121′ apart in this situation so that the displacement can be carried out unimpeded a spring 133 (only shown schematically) can be arranged therebetween.

(23) Locking parts 120, 121 or hinge parts 133, 134 can otherwise also be provided with co-acting stop means (not shown here) for bounding the relative rotation.

(24) In this way hinge parts 133, 134 and the frame parts connected thereto can thus quickly and easily be placed in a desired relative position and be fixated in this position in reliable manner. The number of possible positions is here bounded only by the number of teeth of the toothings 122, 123. In the shown embodiment toothings 122, 123 each have 60 teeth, whereby an angle between the frame parts can be adjusted in steps of 6°. Hinge parts 133, 134 can otherwise also be provided with markings (not shown here) with which a number of preferred settings is indicated. The two hinges 108 on either side of frame 102 can thus be placed in the same position in simple manner.

(25) When a less accurate adjustment is necessary, it is possible to suffice with a simpler locking mechanism. FIG. 5 shows schematically a hinge 208 which connects two frame parts 203, 205 to each other. Hinge 208 comprises two hinge parts 233, 234 which are connected rotatably to each other by means of a central pin 228 and opening 229. In this embodiment a locking part 220, which is connected to hinge part 233, has only three recesses 222A for setting the angle of the backrest, and an additional recess 222B for fixating the frame in the collapsed position. The other locking part 221, which is connected to hinge part 234, is here provided with a single protrusion, for instance a spring-loaded pin 223. By pulling pin 223 from one of the recesses 222 counter to the force of the spring (not shown) hinge 208 is unlocked and locking parts 220, 221 can be rotated relative to each other until pin 223 is aligned with another recess 222. Pin 223 can then be inserted into this recess 222 in order to block locking parts 220, 221 relative to each other again. In this embodiment the frame parts 203, 205 are otherwise mounted on the outer side of the corresponding hinge parts 233, 234 and run over an axis defined by pin 228 and hole 229.

(26) Other locking mechanisms can also be envisaged, such as for instance in the form of a hinge with a ratchet function.

(27) According to a main aspect of the invention, seat 101 is distinguished from the known seat 1 of FIGS. 1-3 in that hinge 108 is embodied as structural component and consists of two load-bearing hinge parts or bodies 133, 134. Each load-bearing hinge body 133, 134 here comprises a central part 135, 136 which carries the toothing 122, 123 of the corresponding locking part 120, 121. In the shown embodiment this central part 135, 136 takes a cylindrical form. Each hinge body 133, 134 further comprises two spacers, respectively 137A, 137B and 138A, 138B, which extend in substantially opposite direction from central part 135, 136. Central parts 135, 136 and spacers 137A, 137B, 138A, 138B can be manufactured from the same material or from different materials. Materials which can be envisaged are steel, light metal and plastics, optionally fibre-reinforced. In the embodiment shown here each central part 135, 136 is cast integrally with the corresponding spacers 137A, 137B, 138A, 138B from aluminium.

(28) In the shown embodiment spacers 137A, 137B and 138A, 138B are in each case mounted on central part 135, 136 staggered relative to each other, so that the frame parts come to lie adjacently of each other in the collapsed position (FIG. 8). In order to still ensure an optimal transfer of forces between spacers 137A, 137B, 138A, 138B and central part 135, 136 the spacers are in the shown embodiment provided with a substantially Y-shaped outer end, whereby a shore 149A, 149B, 150A, 150B is in each case formed. Each shore 149, 150 runs from a position roughly on the central axis of the relevant spacer 137, 138 to a position in the centre of the central part 135, 136, whereby shores 149, 150 run slightly obliquely in top view (FIG. 10). In order to create sufficient space here for these shores 149, 150 when frame 102 is collapsed, the Y-shaped outer ends of spacers 137A, 137B, 138A, 138B are in the shown embodiment provided with a flattened inner surface—wherein only the inner surfaces 151A, 151B of spacers 137A, 137B are visible here. In other embodiments of the load-bearing hinge the spacers can also extend purely radially, as seen from the central axis of the hinge, so that they thus in each case lie pairwise in one line.

(29) Each spacer 137A, 137B and 138A, 138B has here at its free outer end a mounting point, respectively 139A, 139B and 140A, 140B, with which a frame part can be mounted on the load-bearing hinge 108. In the shown embodiment each mounting point 139A, 139B, 140A, 140B comprises a narrowed end part of the relevant spacer 137A, 137B, 138A, 138B, over which a tubular frame part can be placed. The diameter of the narrowed part is adapted to the inner diameter of the tubular frame part such that the frame part can slide thereover close-fittingly and is thus clamped fixedly to hinge 108.

(30) In the shown embodiment the outer ends of spacers 137A, 137B, 138A, 138B are further provided with means for securing the frame tubes placed thereover. Formed in each end part, which takes a hollow form, is a hole 152A, 152B, 153A, 153B in which a pressing member 154A, 154B, 157 is arranged (FIG. 9). Each pressing member 154A, 154B, 157 is urged outward by a flexure spring 155A, 155B, 156A, 156B received in the hollow end part, and then engages in a recess or groove on the inner side of a tubular frame part. The frame parts are thus mounted on load-bearing hinge 108 firmly and without clearance, yet still in easily releasable manner. Spacers 137, 138 all take a slightly curved form so that mounting points 139, 140 at their free outer ends all lie in the same plane, which is defined by toothings 122, 123 of locking parts 120, 121.

(31) The tubular frame parts can otherwise also be manufactured from the same material or from different materials. Materials which can be envisaged are once again steel, light metal and (optionally fibre-reinforced) plastics.

(32) Because hinge 108 is embodied as a load-bearing structure, and the frame parts can be mounted thereon, the frame parts can also take a smaller form than in the prior art seat 1. While frame parts 3, 5 of known seat 1 still extend on either side of hinge 8, and hinge 8 thus in fact protrudes through frame parts 3, 5, this is different in seat 101 according to the invention. The frame parts are now as it were interrupted at the position of hinge 108, whereby their height is almost halved.

(33) As can be seen in FIG. 11, frame 102 of seat 101 can be assembled by mounting frame parts 103, 105, 141 and 142 from four sides on the four spacers 137A, 137B, 138A, 138B of hinge 108. Seat 101 comprises here two of such hinges 108 so that frame parts 103, 105, 141, 142, which are substantially U-shaped, are connected to each other in an X-shape on either side of seat 101. After frame parts 103, 105, 141, 142 have thus been connected to each other, backrest 104 can be arranged on first frame part 103 and seat surface 109 can be tensioned between the first and second frame part 103, 105. Backrest 104 and seat surface 109 are here in the shown embodiment formed integrally from textile material.

(34) Because seat 101 according to the invention comprises four frame parts 103, 105, 141, 142 rather than two frame parts 3, 5 for the known seat 1, it can be stored or packaged smaller in disassembled state.

(35) In order to enable seat 101 to be packaged smaller still, frame parts 103, 105, 141, 142 can themselves also be taken apart into smaller components. Each frame part can thus be constructed from three tubes which are connected to each other by means of two corner pieces into a U-shaped frame part. This can be seen in FIG. 4 for lower frame part 141 on the rear side of seat 101, which is constructed from two tubes 143 which are mounted on hinges 108, and a transverse tube 144 which extends parallel to a connecting line between hinges 108. Tubes 143, 144 are connected to each other by means of corner pieces 145 which also function as feet, which make seat 101 stable. Lower frame part 142 on the front side of seat 101 has a similar construction, while first frame part 103 and second frame part 105 in the shown embodiment also consist of tubes which are connected releasably to each other. In the case of first frame part 103 the transverse tube per se has a U-shape here, and each leg thereof is connected at the position of a bend 146 in first frame part 103 to another tube.

(36) The option of assembling seat 101 from a number of relatively short tube parts which are connected into a stable whole by the load-bearing hinges 108 enables seat 101 to be stored or packaged and transported in a relatively small space. For seat 101 it is thus possible to suffice with a packaging 147, the dimensions of which amount to about half of those of a packaging 148 for conventional seat 1 (FIG. 12).

(37) The invention thus provides a seat which provides an improved functionality and can furthermore be packaged smaller than the known seat. It should otherwise be noted that all the above described new features of the seat according to the invention can per se form essential components of the invention, which can be applied in different combinations. The load-bearing hinge as described here can thus also be applied without locking, in combination with a seat with a folded-out position which is determined by straps/armrests, while the locking of the hinge could on the other hand also be applied in a conventional seat with two different frame parts as shown in FIGS. 1-3.

(38) The scope of the invention is therefore defined solely by the following claims.
