Abstract
Vehicle seat devices are provided with: a backrest; side supports that are disposed on both sides of the backrest, and that have protruding sections that protrude further forward than the backrest; a mechanism for adjusting the degree of restraint that changes the width of the protruding sections; a frame disposed inside the side supports; and a movable member that is disposed on the frame, and that displaceably holds the ends of a side surface leather material of the side supports in relation to the frame.
Claims11
A vehicular seat device comprising:
- a backrest;
- side supports disposed on respective sides of the backrest and having respective protrusions that project forwardly of the backrest, the side supports including respective covering layers;
- engaging members mounted respectively on the ends of the covering layers, the engaging members extending in one direction;
- means for variably changing widths of the protrusions;
- a frame disposed in the side supports;
- and
- a movable assembly mounted on the frame and comprising a flexible member which is fixed to the frame, wherein the flexible member includes engaging wires which extend along a direction in which the backrest extends, and which are engaged by the engaging members;
- wherein respective ends of the covering layers are held by the movable assembly for displacement with respect to the frame,
- and wherein the flexible member engages with the ends of the covering layers, and is elastically deformable to displace the ends of the covering layers toward projected ends of the protrusions, as widths of the protrusions are changed.
A vehicular seat device comprising:
- a backrest;
- side supports disposed on respective sides of the backrest and having respective protrusions that project forwardly of the backrest;
- at least one inflatable pouch member in each of the protrusions for variably changing widths of the protrusions;
- a frame disposed in the side supports;
- and
- a movable back support assembly mounted on the frame and comprising a pressure-bearing member disposed in the backrest, and a flexible wire member which is attached to the pressure-bearing member, the flexible wire member disposed behind the pressure-bearing member and including two substantially vertically extending engaging wire segments;
- wherein the side supports include respective covering layers, respective ends of the covering layers being held by the movable back support assembly for displacement with respect to the frame,
- and wherein the flexible wire member engages with the ends of the covering layers at the substantially vertically extending segments, and the flexible wire member is elastically deformable to displace the ends of the covering layers forwardly toward projected ends of the protrusions, as widths of the protrusions are changed.
