Definitions

  • This invention relates to reclining apparatus for supporting a human body according to the first part of claim 1.
  • Such a reclining apparatus realized as a chair is known from GB-A-1,403,648.
  • an angular rod is fixed at a seat member which is slidable in a groove of a fixing element which is protatably mounted at a support member.
  • these two parts can not get jammed because of the rotatably mounting of the fixing element. Therefore, the different seat positions are not fixed shurely enough especially if the rod takes a more vertical position.
  • the angular rod and the fixing element are relatively complicated mecanical parts which damage the appearance of the chair. High production costs are further disadvantages of this construction.
  • the object of the invention is to provide a simply constructed and uncostly manufactured reclining apparatus which steplessly can be locked in a desirable reclining position.
  • the lock member of the reclining apparatus comprises at least one rod movingly mounted at one of said seat member, said back member and said support member and slidingly guided across in at least one aperture of another one of them, whereby said rod being unlocked and slidable in the aperture in response to a force applied to an upper portion of said back member.
  • the lock member When a force is applied only to the seat member, the lock member is locked to maintain the angle between the seat member and the back rest member. On the other hand, when a force is applied to both the seat member and the back rest member, the lock member is unlocked and moves to change the angle between the seat member and the back rest member.

Abstract

Structure rabattable (1, 21, 41, 61) dans laquelle des éléments de support (2, 22, 42, 62), un élément de siège (3, 23, 43, 63) et un élément de dossier (5, 25, 45, 55, 75) sont reliés entre eux librement, au moins deux types d'éléments parmi lesdits éléments de support, l'élément de siège et l'élément de dossier étant reliés entre eux par une tige (11, 31, 51, 71) d'un organe de verrouillage (13, 33, 53, 73), la tige étant disposée de manière à croiser l'un de ces deux types d'éléments. Ces deux types d'éléments sont verrouillés de manière à ne pouvoir être déplacés l'un par rapport à l'autre sous l'effet d'une force appliquée uniquement entre l'élément croisé par la tige et cette dernière. Par conséquent, afin de rajuster la structure rabattable, l'utilisateur modifie sa position sur une chaise (1, 21, 61) ou sur un lit (41) afin de libérer l'élément croisé par la tige et cette dernière de la force appliquée entre ces deux éléments, pour faire en sorte que les éléments de support, l'élément de siège et l'élément de dossier, qui constituent la structure rabattable, puissent se déplacer librement. A la fin de l'opération de rajustement, l'utilisateur s'assied ou s'allonge sur l'élément de siège pour provoquer le verrouillage entre l'élément croisé par la tige et cette dernière.
