Abstract
Disclosed is a vehicle seat (1) comprising a seat cushion (2) and a seat back (4), wherein the seat cushion and the seat back are comprised of: a frame structure (8) to be fixed to the vehicle body; and a seating member (10) supported by the frame structure having an elastic deformation property and a vibration damping property and allow an occupant to be seated therein, and wherein the vehicle seat satisfies the following relationship: DS/DF≥20, where DS denotes a deformation amount of the seating member itself in a situation where a load W is applied at a position XS of the seating member, and DF denotes a displacement of a position XF of the frame structure corresponding to the position XS, in a situation where the frame structure is fixed to the vehicle body, and the given load W is applied at the position XF.
Claims5
A vehicle seat mountable to a vehicle body of a vehicle and comprising a seat cushion and a seat back, the vehicle seat comprising:
- a frame structure to be fixed to the vehicle body;
- and
- a seating member supported by the frame structure and configured to have a given elastic deformation property and a given vibration damping property and allow an occupant to be seated therein,
- wherein the vehicle seat satisfies the following relationship:
- DS/DF≥20, where DS denotes a deformation amount of the seating member itself in a situation where a given load W is applied at a given position XS of the seating member, and DF denotes a displacement amount of a position XF of the frame structure corresponding to the given position XS, in a situation where the frame structure is fixed to the vehicle body, and the given load W is applied at the position XF.
A design method for a vehicle seat mountable to a vehicle body of a vehicle and comprising a seat cushion and a seat back, the vehicle seat comprising:
- a frame structure to be fixed to the vehicle body;
- and a seating member supported by the frame structure and configured to have a given elastic deformation property and a given vibration damping property and allow an occupant to be seated therein, the design method comprising the steps of:
- designing the seating member, and determining, by measurement or calculation, a deformation amount DS of the designed seating member itself in a situation where a given load W is applied at a given position XS of the designed seating member;
- designing the frame structure, and determining, by measurement or calculation, a displacement amount DF of a position XF of the designed frame structure corresponding to the given position XS, in a situation where the designed frame structure is fixed to the vehicle body, and the given load W is applied at the position XF;
- and
- checking whether or not the deformation amount DS and the displacement amount DF satisfy the following relationship:
- DS/DF≥20, and, if not, modifying the seating member, the frame structure, and/or a mounting structure of the frame structure to the vehicle body, so as to satisfy the relationship:
- DS/DF≥20.
