Abstract
The invention relates to a vehicle seat comprising a base portion for attachment in a vehicle; a seat bottom part, with a top side and an underside, which seat bottom part is attached to the base portion; a waist belt, which extends between the seat bottom part's sides. At least one hinge mechanism that is adjustable between a first and a second position is arranged at the base portion. The waist belt is attached to the hinge mechanism, so that the waist belts position in relation to the seat bottom part changes when one on the seat bottom part acting force reaches a predetermined value, which force leads the hinge mechanism from the first to the second position.
Claims10
Vehicle seat comprising:
- a base portion for attachment in a vehicle;
- a seat bottom part, with a top side and an underside, which seat bottom part is attached to the base portion, wherein the top side of the seat bottom part comprises a resilient support surface, which is arranged at and supported by an at least partially around a support surface surrounding frame;
- a waist belt extending between the seat bottom part's sides, and
- at least one hinge mechanism, that is adjustable between a first position and a second position, arranged at the base portion,
- wherein the waist belt is attached to the hinge mechanism,
- an actuator extends substantially parallel with the seat bottom part's underside and is attached to the at least one hinge mechanism, so that the actuator moves the hinge mechanism from the first position to the second position, and
- a position of the waist belt in relation to the seat bottom part changes when a force acting on the seat bottom part reaches a predetermined value so as to make the actuator move the hinge mechanism from the first position to the second position, the force being a downwards acting force generated by mass inertia of a person sitting in the seat when the seat moves at a high speed upwards.
