Vehicle seat and method of manufacturing the same

A vehicle seat comprising:

• a planar elastic body that has a frame body provided in a periphery of the planar elastic body, the periphery of the planar elastic body being disposed within the frame body such that the frame body surrounds the periphery of the planar elastic body, the planar elastic body being stretched to the frame body;
• a cushion member disposed around the planar elastic body;
• and
• a backbone member having a first side end provided at the frame body and a second side end that projects away from the frame body in a direction generally orthogonal to the planar elastic body, wherein
• the planar elastic body and the cushion member define a supporting surface configured to support a seated person,
• the frame body includes a recess configured to engage with the backbone member such that the planar elastic body is assembled to the seat,
• the cushion member is disposed to be overlaid on the periphery of the planar elastic body at a supporting surface side, and
• the cushion member is covered by a skin material, the skin material having a first end portion that is directly attached on the planar elastic body at the supporting surface side and a second end portion provided at an opposite side of the supporting surface side with an engagement member that is attached to the second side end of the backbone member.
