- a seat firmness of the seat device can be adjusted without the upholstery unit and/or the tray element having to be replaced.
- the seat device can be easily and inexpensively adjusted to the needs of different users of the vehicle.
- the vehicle can include a watercraft, aircraft or a land vehicle, in particular a truck, a passenger car or a tilting vehicle.
- a tilting vehicle is understood to mean bicycles, motorcycles or motor vehicles similar to motorcycles, such as motor scooters, in particular two-, three- or four-wheeled motor scooters, scooters, tiltable trikes, quads or the like.
- the at least one spring means of the spring unit can be positioned easily and captively in or on the tray element if the tray element has a receptacle comprising a cavity, which is arranged in or on the tray element and into which the at least one spring means can be manually or automatically inserted along a joining direction and fixed against springing or limited from springing.
- the spring means is fixed in the receptacle against movement in the spring direction or movement in the spring direction is limited, it is ensured that the at least one spring means acts with its spring force between the cushion unit and the tub element.
- the tub element comprises an opening on a surface extending transversely or obliquely to the seat surface, through which at least one of the at least one spring means can be inserted into the receptacle, and the joining direction runs transversely or at an angle to the spring direction and/or in which the cushion unit can be converted from a fixed arrangement into an open arrangement relative to the tub element, in which the receptacle is accessible from the outside and at least one of the at least one spring means can be inserted into the receptacle, and the joining direction is in or at an angle to spring direction and/or in which the tray element comprises a recess on the side facing away from the upholstery unit, through which at least one of the at least one spring means can be inserted into the receptacle, and the joining direction runs in or at an angle to the spring direction.
- the tub element has an opening on a surface that extends transversely or at an angle to the seat surface, through which at least one of the at least one spring means can be inserted into the receptacle and the joining direction runs transversely or at an angle to the spring direction, the at least one spring means can be pushed into the tub element parallel to the surface of the seat surface.
- the at least one spring means can be inserted into the receptacle in the tray element parallel or at an angle to a transverse axis of the vehicle or transversely or at an angle to a longitudinal axis of the vehicle.
- the cushion unit can be converted from a fixed arrangement to an open arrangement relative to the tub element, in which the receptacle is accessible from the outside and at least one of the at least one spring means can be inserted into the receptacle and the joining direction runs in or at an angle to the spring direction, the at least one spring means can be inserted into the receptacle parallel to a vertical axis of the vehicle. After the at least one spring means has been inserted into the receptacle in the tub element, the upholstery unit is then transferred from the open arrangement back into the fixed arrangement in which the upholstery unit is fixed in place with respect to the tub element.
- the tub element has a recess on the side facing away from the upholstery unit, through which at least one of the at least one spring means can be inserted into the receptacle and the joining direction runs in or at an angle to the spring direction, the at least one spring means can be inserted into the tub element from below.
- the joining direction is also parallel to a vertical axis of the vehicle.
- the spring unit comprises at least two spring means which are arranged at an angle or parallel to one another.
- the firmness of the seat can be increased by additionally arranging further spring means. If at least two of the at least two spring means run parallel to one another, they can be arranged in the same receptacle or in two receptacles running parallel to one another.
- At least two of the at least two spring means from the are formed from the same material or from different materials, with at least one of the at least two spring means comprising a metal or a plastic and/or when at least two of the at least two spring means comprise the same spring rate or at least two of the at least two spring means each comprise a different spring rate.
