In Fig. 4 2, the supporting device 2 is shown, with some slats being omitted for the purpose of illustrating details of the electromechanical loading / unloading device 26.

In this embodiment, in addition to the loading / unloading device 26, a further loading / unloading device 26 'is provided. The loading / unloading devices 26, 26 'are arranged spaced apart from one another in the longitudinal direction of the support device 2 in order to allow a massaging effect in different areas in the longitudinal direction of the support device 2.

Both loading / unloading devices 26, 26 'have the same structure. Therefore, only the loading / unloading device 26 will be explained in more detail below. For illustration purposes is in Fig. 4 to Fig. 7 only the loading / unloading device 26 shown, while the loading / unloading device 26 'is omitted.

As in Fig. 5 illustrated, the loading / unloading device 26, the first carriage 28 which is part of the first linear drive and is movable in the longitudinal direction of the support means 2 along a linear axis. The linear axis is defined by a first linear guide 44 which extends in the longitudinal direction of the support means 2.

The first carriage 28 is in driving connection with the first electric motor 34, wherein the first carriage 28 carries the arm 33 (see. Fig. 5 and Fig. 6 ), whose free end carries the pressure element 36 for loading and unloading the slats 22, 24. The pressure element 36 is formed in this embodiment as a wheel or roller which is rotatably mounted relative to the arm 33 and on which the slats 22, 24 opposite side of the belt 40 is applied. (see in particular Fig. 6 ).

In the illustrated embodiment, the first carriage 28 carries two arms, namely the arm 33 and a further arm 33 ', wherein each of the arms 33, 33' carries a pressure element 36 or 36 '. The pressure elements 36, 36 'are relative to each other transversely to the longitudinal direction of the support means 2 spaced apart, as in particular from Fig. 6 seen.

The pressure elements 36, 36 'are adjustable relative to the support plane defined by the slats 22, 24, wherein the adjustment drive 38 is provided to adjust the pressure elements 36, 36' relative to the support plane.

On the first carriage 28, a pivot shaft 46 is pivotally mounted (see. Fig. 6 ), with which the arms 33, 33 'are rotatably connected. The adjustment 38 is designed to pivot the pivot shaft 46 about its pivot axis to adjust by pivoting the arms 33, 33 ', the pressure elements 36, 36' relative to the slats 22, 24. Accordingly, the arms 33, 33 'have the function of pivoting levers.

In order to move the first carriage 28 along the first linear guide 44, the first linear drive has a first spindle drive 48 (cf. Fig. 6 ) on. The first spindle drive 48 has a first threaded spindle, which extends in the longitudinal direction of the first linear guide 44 and is mounted against rotation. A first spindle nut is mounted on the first threaded spindle and is connected via a worm gear in rotational drive connection with the output shaft of the first electric motor 34. The first spindle nut is housed together with the worm gear and the output shaft in the first carriage 28 which is formed like a box.

Upon rotation of the output shaft of the first electric motor 34, the first spindle nut rotates. Accordingly, the first carriage 28 moves along the first linear guide 44 in one or the other direction according to the rotation direction of the spindle nut, whereby the first carriage 28 is positioned with the pressure elements 36, 36 'in the longitudinal direction of the first linear guide, so that at the corresponding location slats 22, 24 are acted upon by the pressure elements 36, 36 'for loading / unloading the respective slats 22, 24th

Running parallel to the first linear guide 44 is a second linear guide 50 (cf. Fig. 5 ) intended. On the second linear guide 50, a second carriage 52 is guided in the longitudinal direction of the support means 2.

The pivot shaft 46 is pivotally connected to the second carriage 52. The second carriage 52 is thus connected by means of the pivot shaft displaceable with the first carriage 28. Accordingly, the carriages 28, 52 move synchronously as the first carriage 28 moves upon actuation of the first electric motor 34.

With reference to Fig. 7 will be explained in more detail below the adjustment 38.

The adjusting drive 38 has a second linear drive with a second electric motor 54 and a second spindle drive 56.

On a second threaded spindle of the second spindle drive 56, a second spindle nut 58 is disposed against rotation. Upon actuation of the second electric motor 54, the second threaded spindle rotates, so that the second spindle nut 58 moves in the axial direction of the second threaded spindle in one or the other direction according to the direction of rotation of the second threaded spindle.

As in Fig. 7 is shown, for rotating or pivoting the pivot shaft 46 about its pivot axis in a linear movement of the second spindle nut 58, a connecting plate 60 is provided. A first end of the connecting tab 60 is pivotally connected to the second spindle nut at a first pivot point 62, while a second end of the connecting tab 60 is connected to a second pivot nut 62 second pivot point 64 is connected to the pivot shaft 46, and eccentric to the pivot axis, such that the pivot shaft 46 pivots in a linear movement of the second spindle nut 58.

For controlling the electric motors 34, 54 is a control device 64 (see. Fig. 2 ) intended.

Upon actuation of the first electric motor 34, the carriages 28, 52 are positioned relative to the slats 22, 24 along the linear guides 44, 50 to bias the slats 22, 24 in the respective area.

Upon actuation of the second electric motor 54 pivots the pivot shaft 46 so that the pressure elements 36, 36 'act on the respective slats by pressure load. The intensity of the resulting massage effect is controllable by controlling the pivoting angle.
