Abstract
An arrangement for a seat intended to be fitted in the back-rest of the seat in order to massage the back of a person sitting in the seat. The arrangement comprises two identical pulsators (5) intended to be accommodated in recesses in the padding material of the seat. Each pulsator (5) comprises an electrical drying motor (11) for driving a number of massage elements (29-32). The driving motors (11) are connected to a common electrical control system which, during a time-limited work cycle, intermittently supplies the driving motors (11) with voltage.
