Abstract
The disclosure relates to a seat for a vehicle. The seat may have a seat structure having at least a backrest frame part adjustable between an initial position and at least an inclined position. The seat may also have a seat adjusting device having at least a number of linear actuators. Further, the disclosure relates to a seat mounting structure having such a seat.
Claims13
A seat for a vehicle, the seat comprising at least:
- a seat structure having at least a backrest frame part adjustable between an initial position and at least an inclined position, and
- a seat adjusting device having at least one linear actuator, the at least one linear actuator is at least mounted to the backrest frame part via a respective single pivot connection,
- wherein the seat adjusting device comprises a coupling mechanism providing an external pivot axis arranged behind the backrest frame part and which is relatively coupled with the at least one linear actuator and the backrest frame part,
- wherein actuation of said at least one linear actuator initiates movement of the backrest frame part with respect to the external pivot axis,
- wherein the coupling mechanism comprises a fixed coupling bar and two coupling elements each pivotable coupled to one side of the coupling bar and each coupling element comprises at least two connection areas,
- wherein one connection area is coupled to the backrest frame part and to the at least one linear actuator and the other connection area is coupled to the coupling bar.
3 more elements
A seat mounting structure for a vehicle, the seat mounting structure comprising at least:
- a seat rib cage which comprises integrated seat mounting points, vehicle structure mounting points and mounting locations for seat adjusting devices, and
- a seat having a seat structure with at least a backrest frame part adjustable between an initial position and at least an inclined position, and
- a seat adjusting device having at least one linear actuator, the at least one linear actuator is at least mounted to the backrest frame part via a respective single pivot connection,
- wherein the seat adjusting device comprises a coupling mechanism providing an external pivot axis arranged behind the backrest frame part and which is relatively coupled with the at least one linear actuator and the backrest frame part,
- wherein the coupling mechanism is coupled to the mounting location of the seat rib cage,
- wherein actuation of the at least one linear actuator initiates movement of the backrest frame part with respect to the external pivot axis,
- wherein the coupling mechanism comprises a fixed coupling bar and two coupling elements each pivotable coupled to one side of the coupling bar and each coupling element comprises at least two connection areas,
- wherein one connection area is coupled to the backrest frame part and to the at least one linear actuator and the other connection area is coupled to the coupling bar.
5 more elements
A seat for a vehicle, the seat comprising at least:
- a seat structure having at least a backrest frame part and a seat pan frame part both being adjustable between an initial position and at least an inclined position, and
- a seat adjusting device having at least a number of linear actuators,
- a first number of linear actuators is mounted to the backrest frame part via a respective single pivot connection,
- a second number of linear actuators is mounted to the seat pan frame part via a respective single pivot connection,
- wherein the seat adjusting device comprises a coupling mechanism providing an external pivot axis arranged behind the backrest frame part and which is relatively coupled with the second number of linear actuators and the backrest frame part,
- wherein each linear actuator is individually actuatable or actuatable with other linear actuators from said number of linear actuators whereas depending on an individual actuation or a combined actuation of more than one linear actuator the seat structure is relatively movable with respect to the external pivot axis in at least one degree of freedom up to a plurality of degrees of freedom,
- wherein the seat pan frame part and the backrest frame part are configured as one-piece frame.
