ARRANGEMENT FOR USE OF A FUNCTIONAL SEAT

摘要

The invention relates to an arrangement for use of a functional seat, which seat is intended particularly for assisting a person sitting thereon to stand up from a sitting position. The arrangement comprises a seat part (1) provided/to be provided in connection with a sitting base (A) and being coupled in a power transmitting manner with armrests (1a) of the seat, wherein the seat part (1) is arranged by a movement mechanism (x) simultaneously on the other hand to incline from an essentially horizontal sitting-position (I) to a standing up-position (II), where the seat part is inclined down ward toward its front edge, and on the other hand to move upward while being inclined to the standing up-position (II) from the sitting-position (I) particularly in order to enable assisting a standing up-movement, advantageously by influence of the person him-/herself sitting on the seat part (1), by exploiting his/her upper body through using hand force. The arrangement comprises driving means (y), including at least a locking assembly (y1) for an locking the seat essentially immovably to its sitting-position (I) and a releasing assembly (y2) for reinstating the movement function of the seat by releasing it from its sitting-position (I), wherein releasing assembly (y; y2) of the driving means is arranged to operate by influence of the power directed to the seat part (1) from the person sitting on the seat, in order to activate the movement function of the seat automatically when the person is sitting on the seat.

1. An arrangement for use of a functional seat, which seat is intended particularly for assisting a person sitting thereon to stand up from a sitting position, wherein the arrangement comprises a seat part (1) provided/to be provided in connection with a sitting base (A) and being coupled in a power transmitting manner with armrests (1 a) of the seat, wherein the seat part (1) is arranged by a movement mechanism (x) simultaneously on the other hand to incline from an essentially horizontal sitting-position (I) to a standing up-position (II), where the seat part is inclined downward toward its front edge, and on the other hand to move upward while being inclined to the standing up-position (II) from the sitting-position (I) particularly in order to enable assisting a standing up-movement, preferably by influence of the person him/herself sitting on the seat part (1), by exploiting his/her upper body through using hand force, and, wherein the arrangement furthermore comprises at least partly independently functional driving means (y), operating by power (W) that is directed to the seat part (1) from the person sitting on the seat, the driving means comprising at least a locking assembly (y1) for locking the seat part essentially immovably to its sitting-position (I) and a releasing assembly (y2) for reinstating the movement function of the seat part by releasing it from its sitting-position (I), characterized in that, the releasing assembly (y; y2) of the driving means is arranged to operate by influence of the power W directed to the seat part 1 from the person sitting on the seat in order to activate the movement function of the seat automatically when the person is sitting on the seat.
