An accessory 4 for a vehicle seat 1 with a squab 2 and backrest 3, the accessory 4 comprises a first element 5, 6 to be mounted in or on (fig. 10) the squab 2 of the seat 1 and a second element 7, 8 mounted in or on the backrest 3. Pressure on the first element 5, 6, for example induced by the weight of person occupying the seat 1, causes horizontal displacement of the second element 7, 8, possibly to allow the second element 7, 8 to provide extended support in the lumber / pelvic / shoulder region of a person occupying the seat. The elements 5, 6, 7, 8 may comprise fluid sacs, possibly filled with air and interconnected by a fluid duct 9. The elements 5, 6, 7, 8 may alternatively comprise linkage (23, 24, 25, fig.7) connected plates (20, 21, fig.7). Alternatively, the first element 5, 6 may comprise a sensor / actuator arrangement (fig.9) to activate the horizontal displacement in the second element 7, 8, for example, sourced from a separate gas supply. The second element may be positioned in a lumbar (figs. 1 and 2) shoulder (figs. 3 and 4) or pelvic (figs. 5 and 6) support regions. |
