PROBLEM TO BE SOLVED: To facilitate an adjustment of a pressure distribution in a direction of height of backbone at a support plate for a backrest of a vehicular seat by installing a pressure distribution element adjustable in the height direction that is arranged as operatable between the support plate and a pressure plate. SOLUTION: A pressure distributing adjustment device has a support plate 1 that is made of a material with bent elasticity and arranged in a cushion of a backrest for a vehicular seat. The support plate 1 is supported by a pressure plate 3 through a pressure distribution element 2. The pressure distribution element 2 is arranged height-adjustably between the support plate 1 and the pressure plate 3, and the pressure plate 3 is arranged revolvable in the backward. A loop material for adjustment 11 is arranged at the lower part of the pressure plate. The modulation of the loop material for adjustment 11 enables the pressure plate 3 to be adjusted in the direction of depth by rotating a revolving axis 12. |
