Abstract
Description
- 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. For locking the seat position 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. However, 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. Moreover, 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.
- In order to achieve this object the lock member of the reclining apparatus according to the invention 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.
- Further features of the invention are defined in
claims 2 to 7. - The advantage of this reclining apparatus according to the invention is a very simple construction which can be manufactured at reasonable costs. Nevertheless the adjustment or regulation comfort is high and the fixing is strong because the rod get jammed in a fixed groove of one of the seat member, the back member or the support 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.
