Support structure for automatic vehicle driving device

A support structure of an automatic vehicle driving device comprising:

• a frame having, at an upper end thereof, a seat back abutting part and extending obliquely downward from the seat back abutting part toward a vehicle front side;
• a pair of legs positioned at a front end of the frame and extending downward along a front end of a seat cushion, wherein lower ends of the legs abut against a vehicle body floor;
• and
• a belt engaged with a middle portion of the frame and providing a tensile load obliquely downward toward a rear end portion of the seat cushion, wherein
• the seat back abutting part is formed by
• a substantially U-shaped main frame linearly extending from connecting portions with the legs and abutting against a relatively lower position of a seat back, and
• a substantially U-shaped sub frame branching off obliquely upward from a middle portion of the main frame and abutting against a relatively upper position of the seat back.

• a substantially U-shaped main frame swelling into a barrel shape in plan view;
• and
• a sub frame located at an inner side of the main frame,
• the legs are each fixed to a front end of the main frame,
• a band-shaped lateral beam of the main frame, which is located at a rear end of the main frame, forms the seat back abutting part, and
• a rear end of the sub frame is connected to the lateral beam of the main frame, and a front end of the sub frame is connected to a front end portion of the main frame.
