Abstract
An adjustable headrest for a seat backrest having a mounting system includes a frame structure adapted to be secured on the mounting system for up and down movement relative to the seat backrest. The headrest also includes a drive mechanism having a height adjustment drive system for controlling height adjustment of the headrest by moving a height adjuster section, and a fore/aft adjustment drive system for controlling fore/aft adjustment by moving the fore/aft adjuster section. The fore/aft drive system has an adjustment member constrained to up and down movement, and the adjustment member is engaged with the adjuster section so as to permit for/aft movement of the adjuster section relative to the adjuster section and the adjustment member.
Claims26
An adjustable headrest, for a seat having a backrest and an associated mounting system, comprising:
- a frame structure adapted to be secured on the mounting system for up and down movement relative to the seat backrest, the frame structure including a height adjuster section and a fore/aft adjuster section, the fore/aft adjuster section being engaged with the height adjuster section for relative movement providing fore/aft adjustment;
- and
- drive means which has a height adjustment drive system for controlling height adjustment of the headrest by moving the height adjuster section and a fore/aft adjustment drive system for controlling fore/aft adjustment of the headrest by moving the fore/aft adjuster section;
- wherein
- the fore/aft drive adjustment system has an adjustment member which is constrained substantially to up and down movement and which is engaged with the fore/aft adjuster section so as to permit fore/aft movement of the fore/aft adjuster section relative to the height adjuster section and the adjustment member, wherein
- the fore/aft adjuster section is engaged with the height adjuster section by first engagement means which precludes relative movement between said sections in a direction for height adjustment while enabling relative movement between said sections in a direction for fore/aft adjustment.
An adjustable headrest, for a seat having a backrest and an associated mounting system, comprising:
- a frame structure adapted to be secured on the mounting system for up and down movement relative to the seat backrest, the frame structure including a height adjuster section and a fore/aft adjuster section, the fore/aft adjuster section being engaged with the height adjuster section for relative movement providing fore/aft adjustment;
- and
- drive means which has a height adjustment drive system for controlling height adjustment of the headrest by moving the height adjuster section and a fore/aft adjustment drive system for controlling fore/aft adjustment of the headrest by moving the fore/aft adjuster section;
- wherein
- the fore/aft drive adjustment system has a nut which is constrained substantially to up and down movement and which is engaged with the fore/aft adjuster section so as to permit fore/aft movement of the fore/aft adjuster section relative to the height adjuster section and the nut, wherein
- the fore/aft adjuster section is engaged with the height adjuster section by first engagement means which precludes relative movement between said sections in a direction for height adjustment while enabling relative movement between said sections in a direction for fore/aft adjustment.
