Patent ID: 8840182

Claim:
A seat structure for a vehicle, configured to allow three passengers to be seated side-by-side therein, comprising: a right seat and a left seat which are separated right and left; and a headrest for a middle seat passenger who is seated in a region striding across a boundary between the right and left seats, the headrest for the middle seat passenger being supported on a seat back of one of the right and left seats, wherein: at least one of the right and left seats is slidably moved in a rightward-leftward or frontward-rearward direction so as to allow the right and left seats to become spaced apart from each other to create a walk-through space therebetween, while leaving the headrest for the middle seat passenger projecting into the walk-through space and at least partly blocking the walk-through space; and the middle seat passenger's headrest is slidably moved in a rightward or leftward direction relative to the seat back on which the middle seat passenger's headrest is supported, thereby causing the walk-through space to become unblocked when the right and left seats are in spaced-apart relation.
