Abstract

A motor vehicle seat has a seat cushion angularly movable about a pivot, a backrest angularly movable about a shaft, and a headrest detachably mounted on the backrest, the headrest having a pair of stays extending downwardly. A headrest storage mechanism has a headrest storage space defined between the seat cushion and the backrest when the seat cushion is lifted forward and the backrest is lowered forward toward the seat cushion, with the headrest removed from the backrest, and a pair of arms mounted on the seat cushion and attached to the pivot, for supporting the headrest in a given attitude when the seat cushion is lifted forward. The headrest storage space has such dimensions as to be able to store the stays extending downwardly from the headrest when the headrest is supported on the arms.

Claims

1. A headrest storage mechanism for a motor vehicle seat, comprising:

a seat having a seat cushion angularly movable about a pivot, a backrest angularly movable about a shaft, and a headrest detachably mounted on said backrest, said headrest having a pair of unitary stays extending downwardly from said headrest;

a headrest storage space defined between said seat cushion and said backrest when the seat cushion is lifted forward and the backrest is lowered forward toward the seat cushion, with said headrest having said stays detached from said backrest;

a pair of supporting arms mounted on an underside of the seat cushion and attached to said pivot, said supporting arms extending across said headrest storage space for supporting the headrest in a given attitude when the seat cushion is lifted forward; and

said headrest positioned in said headrest storage space, when said headrest and said pair of stays are detached from said backrest with said headrest supported on said pair of supporting arms and said pair of stays extending downwardly from said headrest past said pair of supporting arms toward a floor of a vehicle.

2. A headrest storage mechanism according to claim 1, wherein said headrest is held by said arms and pressed by said backrest when said headrest is supported on said arms.

3. A headrest storage mechanism according to claim 1, further comprising a vehicle body and a cover mounted on said vehicle body, said seat cushion being angularly movably mounted on said vehicle body for forward lifting movement off said cover.

4. A headrest storage mechanism according to claim 3, further comprising:

lock means mounted on said cover for locking a rear end of said seat cushion on said cover;

said lock means comprising;

a lock member mounted on said cover;

a hook member mounted on said seat cushion and normally biased into engagement with said lock member by a spring; and

a tension string engaging said hook member for being pulled upwardly above the rear end of said seat cushion.

5. A headrest storage mechanism according to claim 1, wherein a top of said backrest is provided with a pair of sockets for detachably receiving said pair of unitary stays solely by slidably inserting and withdrawing said stays into and from, respectively, said sockets.

6. A headrest storage mechanism according to claim 1, wherein said pair of stays are positioned between said pair of supporting arms when said headrest and said pair of stays are supported in said headrest storage space.

7. A headrest storage mechanism according to claim 1, wherein said pair of stays are of a length that is less than a distance from a top of said pair of supporting arms to said vehicle floor whereby said pair of stays do not engage said vehicle floor when said headrest and said pair of stays are supported in said headrest storage space.
