The present invention relate to a vehicle seat (1) having a backrest (3) which is provided to be pivotable on a seat part about a pivot axis.
This application claims priority to U.S. Application Ser. No. 61/643,587, filed May 7, 2012, the entire contents thereof are incorporated herein by reference.
The present invention relates to a vehicle seat having a backrest which is provided to be pivotable on a seat part about a pivot axis.
In automotive engineering, there is a continuous desire to be able to produce a vehicle seat more easily and/or cost-effectively and/or to provide a vehicle seat with improved safety.
It was therefore the object of the present invention to provide a vehicle seat or individual components of a vehicle seat which meet(s) the abovementioned requirements.
The object is achieved by a vehicle seat having a backrest which is provided to be pivotable on a seat part about a pivot axis, wherein an occupant having an H-point sits on the vehicle seat and wherein the pivot axis of the backrest is provided below the H-point.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
This subject matter of the present invention relates to a vehicle seat having a backrest which is arranged in a pivotable manner on a seat part. On the vehicle seat according to the invention there is a seat occupant who has what is known as an H-point, which corresponds to the position of the hip joint of the occupant. According to the invention, it is now provided that the pivot point of the backrest is arranged below the H-point of the seat occupant. As a result, considerably improved ergonomic seat surfaces and/or, in the event of an accident, improved safety properties of the vehicle seat according to the invention are achieved.
Preferably, the pivot axis of the backrest is arranged behind the H-point of the occupant in relation to the direction of forward travel of the vehicle, more preferably, the pivot axis is provided between the H-point and the backrest of the vehicle seat.
Yet a further or preferred subject matter of the present invention is a vehicle seat in which the backrest is lockable at a particular inclination angle in relation to the seat part by way of a locking element, wherein the locking element is provided at least partially in the peripheral region of the side part of the seat part and/or of the backrest.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
Preferably, a form- and/or force-fit-means, in particular a toothing, is integrally provided in the peripheral region of the side past of the seat part and/or the sidepart of the backrest. This form- and/or force-fit-means is preferably part of what is known as a recliner, by way of which the inclination of the backrest can be fixed in a particular position and/or by which the inclination of the backrest of a vehicle seat can be adjusted. Preferably, the form- and/or force-fit-means is provided in a part-circular manner, i.e. segment of a circle, wherein the center of the circle is preferably identical with the pivot point of the backrest of the vehicle seat. The side part of the seat part can be produced from metal and can be for example stamped out, wherein the form- and/or force-fit-means is produced during stamping. The side part may, however, also be a plastics part, in particular a fibre-reinforced plastics part. The form and/or force-fit-means is then preferably part of the mould.
Therefore, a further or preferred subject matter of the present invention is a vehicle seat in which the side part of the backrest and/or the sidepart of the seat part integrally has a form- and/or force-fit-means, in particular a toothing.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
Preferably, the form- and/or force-fit-means is provided in a resilient manner. As a result, noise development can at least be reduced and it is ensured that the form- and/or force-fit-means interacts, for example in a locking manner, with a corresponding form- and/or force-fit-means.
Preferably, the form- and/or force-fit-means is part of a recliner. Particularly preferably, the form- and/or force-fit-means is provided in a part-circular manner.
A further subject matter according to the invention or preferred subject matter of the present invention is a vehicle seat in which the side part of the backrest and/or the sidepart of the seat part integrally has a spring means.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
The spring means can be part of a backrest inclination adjuster, in order to bias one form- and/or force-fit-means against a corresponding (form- and/or force-fit-means. Alternatively or in addition, the spring means can be part of a height adjuster, for example in order to reset the seat surface of the occupant into a raised or lowered position, in the present case, too, the side part can be produced from a metal material or from plastics material, in particular fibre-reinforced plastics material.
Alternatively or additionally, the spring means can be the bearing for the backrest at the seat part.
The spring can be arranged between the seat part and the backrest.
According to a further or preferred subject matter of the present invention, the inclination of the backrest of a vehicle seat is adjustable in relation to a seat part and the backrest is lockable in its respective position byway of a latching pawl, wherein a locking element secures the latching pawl in its locking position and the locking element pulls the latching pawl into the looking position.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
Preferably, the side part of the seat part integrally has a form- and/or force-fit-means, in particular a toothing, which interacts in a latching manner with a form- and/or force-fit-means, in particular a toothing, of the latching pawl.
Yet a further subject matter according to the invention or preferred subject matter of the present invention is a vehicle seat in which the inclination of the backrest is adjustable in relation to a seal part-and the backrest is lockable in its respective position by way of a latching pawl and which has a spring means which is provided between the seat part and the backrest, wherein the spring means is a spiral spring which is arranged in a non-concentric manner with the pivot axis of the backrest.
The disclosure made for this subject matter of the present invention applies in equal measure to the other subject matters of the present invention, and vice versa.
The inventions are explained in the following text on the basis of
In the figures:
The seat part 2 and the backrest 3 are coupled in a pivotable manner by means of an inclination adjusting apparatus 5, wherein a vehicle user can actuate the inclination adjusting apparatus 5, for example by means of an adjusting lever 6 or the like. By means of the adjusting lever 6, the inclination adjusting apparatus 5 can be actuated such that it is possible to set a backrest inclination of the vehicle seat 1. A person skilled in the art will understand that the adjustment of the backrest can also take place in a motorized manner. Furthermore, the inclination adjusting apparatus can operate continuously or discontinuously.
