The invention relates to a motor vehicle seat with a lying function.
Motor vehicle seats of this type generally have a calf support which lifts the legs of the person sitting on the seat and, in the process, supports the calves in the lying position.
In the case of previously known calf supports, the calves cannot be prevented from slipping off, for example during cornering, since the surface of the calf support is flat and is rounded downward on the outside. Therefore, even when small lateral forces occur, for example during cornering, the legs may slip off the calf support.
It is therefore the object of the present invention to provide a motor vehicle seat which permits improved positional securing in particular of the legs of a person located on the seat, in particular when the latter has been set into the lying position.
According to the invention, a motor vehicle seat with a lying function is provided, which is provided with a seat cushion, at the first end region of which a backrest is articulated. An extendable calf support is provided at the second, oppositely arranged end region of the seat cushion.
According to the invention, the calf support is provided with a lifting device by means of which the two outer support plates can be lifted from an inoperative position into a support position in which the support plates protrude beyond the supporting surface of the calf support.
According to the invention, the definition “outer support plates” means that the support plates are located adjacent to the outer longitudinal edges of the calf support.
The outer support plates are preferably lifted as the calf support is being extended, this taking place, for example, during the rotation of a vehicle seat into the lying position, in order to achieve a larger supporting surface of the calf support. When the calf support is extended, the outer support plates then protrude over the supporting surface of the calf support so that the legs of a person using the motor vehicle seat according to the invention can be prevented from slipping off since the legs can be placed against the outer support plates if lateral forces act on the legs.
In a further particularly preferred embodiment, a central plate is arranged between the outer support plates, which central plate can likewise be lifted by means of the lifting device from the inoperative position into an end position corresponding to the support position of the support plates.
In this case, in a particularly preferred embodiment, it is possible to provide a central plate with massage pads, in particular in the form of inflatable air pads, which are arranged on the sides of the central plate that face the support plates.
In order to improve the massage effect even further, it is possible, in a further particularly preferred embodiment, also to provide the support plates with massage pads, in particular in the form of air pads, which are arranged on the sides of the support plates that face the central plate.
When actuated, the massage pads can be filled and emptied by pneumatics, for example an air pump, and can carry out the massage function by means of fluctuations in the quantity of air and pressure.
Further details, features and advantages of the invention emerge from the description below of a particularly preferred exemplary embodiment with reference to the drawings.
An extendable calf support 5 is attached to a second end region 6 of the seat cushion 2.
As emerges from an overall view of
As the sequence of
Preferably, as the calf support 5 undergoes this extension, the lifting device 7 can lift the outer support plates 8, 9 from an inoperative position R shown in
Massage pads 11 to 16 can be attached to the central plate 10, wherein the massage pads 11 to 16 are each arranged on the sides 17, 18 of the central plate 10 that face the support plates 8 and 9, respectively.
The provision of such massage pads on the central plate 10 already enables the calves of a person using the motor vehicle seat 1 to be massaged.
