Abstract
The invention relates to a pneumatic bladder arrangement (300) for a neckrest (N) or cushion support (C) of a seat (S) comprising a base inflatable bladder (320) having a shape mainly elongated along a longitudinal axis (X), at least two side inflatable bladders (330), partially overlapping the base inflatable bladder (320) and positioned so that end regions (R1, R3) of the base inflatable bladder (320) are covered by the side inflatable bladders (330) while a central region (R2) of the base inflatable bladder (320) is not covered by the side inflatable bladders (330). The invention further relates to a neckrest (N), a seat comprising the neckrest (N) and to a seat comprising the cushion support (C).
Claims21
A pneumatic bladder arrangement for a neck rest or cushion support of a seat comprising:
- a base inflatable bladder having a shape mainly elongated along a longitudinal axis;
- and
- at least two side inflatable bladders, partially overlapping the base inflatable bladder and positioned so that end regions of the base inflatable bladder are covered by the side inflatable bladders while a central region of the base inflatable bladder is not covered by the side inflatable bladders;
- wherein at least one of the side inflatable bladders is folded at a folding line in two substantially overlapping portions, so as to form a U-shape, and
- wherein the folding line is substantially perpendicular to the longitudinal axis of the base inflatable bladder.
A neck rest for a seat, the neck rest including:
- a frame, and
- a pneumatic bladder arrangement mounted on the frame, the pneumatic bladder arrangement including,
- a base inflatable bladder having a shape mainly elongated along a longitudinal axis, and
- at least two side inflatable bladders, partially overlapping the base inflatable bladder and positioned so that end regions of the base inflatable bladder are covered by the side inflatable bladders while a central region of the base inflatable bladder is not covered by the side inflatable bladders,
- wherein at least one of the side inflatable bladders is folded at a folding line in two substantially overlapping portions, so as to form a U-shape, and
- wherein the folding line is substantially perpendicular to the longitudinal axis of the base inflatable bladder.
