VEHICULAR SEAT

PROBLEM TO BE SOLVED: To fix a supporting base for supporting a seat removably mounted to the frame portion of the seat neighboring this supporting base with high supporting strength without increasing the number of part items. SOLUTION: A center seat 30 is removably mounted on the supporting base 40 elongating from a left side seat 10. A supporting frame 41 composing the frame of the supporting base 40 is fixed to the frame portion at two points by being inserted into two plate shape members formed as the frame portion of the left side seat 10 passing through in the direction of the plate thickness. However, a supporting frame 42 cannot be inserted into the second plate member because a buckle 10B arranged in the neighborhood of the second plate member becomes an obstacle. However, a supporting bracket Fb for other different functional components is arranged at the position before insertion to the first plate shape member at the insertion position so as to be integrated with the frame portion. As a result, the supporting frame 42 is fixed at two points by being inserted into the supporting bracket Fb and the first plate shape member. COPYRIGHT: (C)2008,JPO&INPIT
