Definitions

• the invention relates to an arm rest for a chair, particularly an arm rest for a vehicle seat, comprising an arm pad and parallel side walls, said pad being mounted on a support, said arm rest being mounted on a guide rail, said rail normally being essentially horizontal and extending through the arm rest under the arm pad and between the side walls, and said arm rest being lockable in different locking positions relative to said rail by forcing means.
• the present invention relates to an arm rest support structure, intended to permit keeping the orientation of the arm rest relative to the horizontal plane unaltered, even when the arm rest is moved up or down, is tilted outwards or inwards relative to the seat, is moved forwards or backwards, or is displaced by some combination of these movements. This makes it possible for the person using the arm rest to adjust it without difficulty to suit his working position, his body size, and his occupation.
• Another object of the invention is to provide an arm rest which is relatively easy to manufacture and which is mountable on and usable with existing driver's seats.
• Fig. 1 is a perspective view illustrating the general features of an arm rest of a chair
• Fig. 2 is a sectional view of the arm rest according to the chosen embodiment of the invention.
• Fig. 3 shows the same arm rest at a different inclination.
• Fig. 1 is illustrated a vehicle seat a_, a back rest thereof b, and a brace c.
• the brace c extends behind the back rest b and forwards along the sides of the seat a.
• the brace c is fitted with an arm rest d.
• the arm rest d comprises an upper part e in the form of an arm pad 1 on top of a support in the form of an extruded aluminum plate 2, Fig. 2, and a pair of sides f and g.
• the arm rest d may be affixed to the guide rail/brace c (the pipe 16) by means of a handle h.
• the arm rest d is shown in greater detail in Figs. 2 and 3.
• the aluminum plate 2 which supports the pad 1, there is a partly cylindrical groove 3 and a space 4, the ends 22 of said space being oval recesses with flat bottoms.
• a bent edge 5 and the space 4 houses a cylindrical rod 6, the ends of which fit said recesses and which is partly enclosed by a grip 7.
• the edge 5 and the grip 7 may be turned relative to said groove 3 and space 4, respectively, and are the upper ends of respective sides 8, 9, said sides consisting of plates which in the initial position according to Fig. 1 extend downwards essentially perpendicularly to the plane of the pad 1.
• a distance piece 15 in the form of an extruded aluminum profile 15. Fully along the distance piece 15 runs a partly cylindrical groove 25, partly enclosing the pipe 16. A pair of lateral extensions on each side of the distance piece have been designated 26,27 and 28,29. The external sides 26a,27a and 28a,29a, respectively, are parallel to each other and to the side walls 8,9.
• the pipe 16 extends essentially horizontally, parallel to the extension of the pad 1, and is attached to the dorsal side of the back rest b according to the art.
• the side plates 8,9 are locked in their respective positions relative to the distance piece 15 and to the pipe 16 by friction between the side plates 8,9 and the surfaces 26a,27a and 28a,29a on the distance piece and by clamping the distance piece 15 to the pipe 16, respectively.
• the pad 1 is locked with respect to the chair assembly.
• the pad 1 may assume, within certain geometrically determined limits, a completely arbitrary position. Its vertical position, its inclination forwards-backwards, its inclination sideways, its position sideways and position forwards-backwards may be varied. These position parameters are also independent of each other.
• the point of reference in the assembly is the pipe 16. This pipe does not necessarily have to be exactly horizontal and neither does it have to be directed exactly straight ahead, since the adjustability of the arm rest may compensate for variations in the position of the pipe relative to the seat of the chair. Figs.
• the side plates are not extendable, but are of constant length. They form the long sides of an elongate parallelogram, the one short side of which is the distance between the hinge joints 3-5 and 4-6. The more the arm rest d inclines, the longer this distance will be, provided the pad 1 and its support plate 2 remain at a constant angle to the horizontal plane. This is made possible by letting the rod 6, which is part of one of the two hinges, move freely in the oval recesses 22.
