Self-adapting lath bottom for example for beds and chairs, said lath bottom having at least two frame beams (1), to which are attached with bearings rope sheaves (3) over which run ropes (4) supporting, with the help of other rope sheaves (5) and support members (14), laths (2) connected with one another. It is the intention of the invention to bring about a steady and reliable lath bottom and its rope apparatus. In a lath bottom structure in accordance with the invention, the frame beam (1) consists of a minimum of two adjoining, parallel plates (13), of which the gap is fitted with support rope sheaves (3) and other ropes sheaves (5) made to move with the bottom ends of the support members (14) between the frame plates only in a vertical direction or in a corresponding direction if the frame beam (1) is in a position other than horizontal. |
