Definitions

  • the invention relates to a chair, in particular an office chair. Furthermore, the invention relates to a seat arrangement, in particular for an office chair.
  • the chairs have long been known through public prior use.
  • the chairs can include seats that are adjustable in their inclination.
  • the EP 1 310 227 A2 discloses a seatable device for assisting a user in standing up.
  • the seat assist device comprises a seat carrier and a seat, which are hinged together at a pivot point.
  • the drive nut is firmly connected to a cross member.
  • the cross member interacts with the seat carrier. An axial movement of the cross member causes a tilt adjustment of the seat.
  • the invention has for its object to provide a chair whose seat in a particularly simple manner adjustable in inclination and is determinable.
  • the seat inclination should be extremely reliable adjustable and fixable.
  • a corresponding seat arrangement should also be created.
  • a seat inclination adjustment device comprises two displaceable by an actuating rod or sliding adjustment slide.
  • the actuating rod and the adjusting slide are each provided with threads that are threaded together to move the adjusting slide.
  • the at least one adjustment ramp of the adjusting slide acts on actuation of the seat for pivoting the same.
  • the at least one adjustment ramp runs obliquely with respect to the movement direction of the adjustment slide.
  • first actuating rod partial thread and a second actuating rod partial thread in different areas of the actuating rod is made possible that two adjusting slide are arranged in different areas of the actuating rod. This allows the adjustment slides attack at different locations on the seat, whereby the tilt adjustment of the seat is particularly reliable and efficient.
  • the adjusting slides are guided synchronously or jointly displaceable by the actuating rod. It is advantageous if the adjusting carriages are displaceably guided on the seat carrier. Conveniently, the actuating rod extends in a transverse direction of the chair between two side regions.
  • the internal thread is formed on a guide channel limiting wall of the adjustment slide.
  • the actuating rod thread is formed as an external thread.
  • the guide channel ensures safe guidance or movement of the adjustment slides on the actuating rod. A reverse arrangement of the thread is alternatively possible.
  • the recliner slide is disposed along the actuating rod between a first position in which a seat is in a low position and a lower position, and a second position in which the seat is in a high position or upper position is, relocatable.
  • the positions are transverse positions of the chair.
  • the adjustment slides in their displacement towards the second position, the seat in its high position.
  • the adjustment slides allow a lowering of the seat when displaced in the direction of the first position.
  • the first actuating rod partial thread is formed in the opposite direction to the second actuating rod partial thread, is made possible that the adjusting slide along the actuating rod both movable toward and away from each other, thereby facilitating seat-tilt adjustment.
  • the embodiment according to claim 6 provides that the seat is secured to the seat support. It is advantageous if the seat is secured both during its adjustment and during its non-adjustment to the seat support.
  • the adjustment fuse preferably forms a seat lift-off fuse. This prevents the seat from the seat support can be lifted.
  • the at least one transfer slope runs obliquely with respect to the direction of movement of the adjustment slide. It can be provided directly on the seat.
  • the transfer bevel may also be formed on a separate component, which is then attached to the seat. It preferably extends obliquely with respect to a horizontal.
  • the transfer slope and the associated adjustment ramp preferably run substantially parallel to each other.
  • guide means is preferably formed as a guide recess. An alternative training as a leadership advantage is possible.
  • the guide means serves to guide the seat during its adjustment.
  • the transfer slope is provided in a first, preferably rear seat region of the seat, wherein the seat is pivotally mounted in a second, preferably front, seat region on the seat support.
  • the seat is preferably pivoted about a pivot axis which is provided in the second seating area for pivotal mounting of the seat. It is an advantage when the pivot axis is also in a front region of the seat support. A reverse arrangement is alternatively possible.
  • the adjustment-securing body according to claim 10 is elongate and extends parallel, but spaced from the adjustment ramp.
  • the transfer bevel has at least one corresponding securing area or securing web for interacting with the at least one adjustment securing body. It is advantageous if the at least one securing area or securing web is arranged between the at least one adjusting securing body and the at least one adjusting ramp.
  • the embodiment according to claim 11 is extremely space-saving and visually appealing.
  • the seat tilt adjustment device is actuated independently of a seat height adjustment device and / or a backrest adjustment device.
  • the seat height adjustment device by means of which the seat height of the seat is adjustable, and / or the backrest adjustment device, by means of which the inclination of a backrest with respect to the seat is adjustable, are preferably also between the seat and the seat Carrier arranged.
