Definitions

  • the present invention generally relates to a motorized system for adjusting the recline position of a vehicle seat using a linear actuator.
  • a variety of vehicle seats are commercially available. In many instances, it is desirable to provide a seat occupant with the ability to adjust the position of the seat back relative to the seat base.
  • a variety of powered seat adjustment mechanisms are available for use on the driver's seat and on the front passenger seat of the vehicle.
  • Known power seat adjusters typically include a seat support frame which supports the seat bottom and the seat back of a vehicle seat. The seat support frame is mounted on an upper track which is connected to the seat support frame and which is slidably mounted on a lower track anchored to the vehicle floor.
  • a recliner assembly employs a first and a second straight toothed rack. Rotation of a horizontal lead screw actuates the first straight rack which is in meshing engagement with the second straight tooth rack. Adjustment of the seat recliner position is accomplished by changing the meshed position of the first rack with respect to the second.
  • Typical recliner mechanisms include relatively expensive components which actuate a complex gear arrangement to translate horizontal motion to angular recliner motion.
  • the present invention is a power seat positioning device for automatically adjusting the reclined angle of an upper seat assembly in relation to a lower seat assembly of a vehicle seat. Further, the present invention provides a direct drive actuator arrangement that maintains the structural integrity of the vehicle seat while reducing the quantity of components.
  • the upper and lower seat assembly is typically a frame like structure which provides a rigid support for the cushions which define the seat back and bottom.
  • the recliner apparatus generally includes the upper seat assembly which is pivotally attached to the lower seat assembly and an actuator assembly.
  • the actuator assembly is preferably attached between the lower seat assembly and the upper seat assembly at a first pivot point and a second pivot point respectively.
  • a single ended reversible electric drive motor is preferably provided.
  • the actuator assembly is attached in a substantially linear relationship with the upper seat assembly.
  • a link member is preferably attached to the- upper seat assembly at the first pivot point. Selective activation of the motor will cause corresponding movement of the link member.
  • the actuator assembly therefore ⁇ applies a force directly between the first and second pivot points, which results in adjusting the reclined angle of the upper seat assembly.
  • the present invention further provides a gearbox arrangement for mounting the drive motor perpendicular to the link member.
  • the electric motor can therefore be mounted along the lower seat assembly while the link member directly actuates the reclined angle of the upper seat assembly.
  • the recliner apparatus of the present invention thus fits within the limited space available beneath a seat in a typical vehicle while providing a stable, reliable and secure recliner system that is not overly bulky or complicated.
  • Figure 1 is a diagrammatic, perspective illustration of a vehicle seat including the recliner apparatus designed according to this invention
  • Figure 2 is an exploded side view of the novel recliner apparatus according to the present invention.
  • Figure 3 is an exploded, perspective view of a motor assembly designed according to this invention.
  • Figure 4 is a perspective view of the recliner apparatus according to the present invention.
  • Figure 5 is a perspective illustration of a horizontal drive mechanism of Figure 4 shown from the opposite direction.
  • a vehicle seat assembly 10 generally shown in Figure 1, includes a seat bottom 12 and a seat back 14 supported with respect to the seat bottom 12 for reclining motion (shown in phantom).
  • a switch assembly 16 is used to adjust the position of the seat 10. The adjustment can be controlled by a mechanical actuator, an electrical actuator, or an electro-mechanical actuator.
  • the switch assembly 16 is preferably an electrical switch assembly that actuates a reclining apparatus 18 to move the seat back 14 and seat bottom 12 between a variety of angular seat positions.
  • the switch assembly 16 is used by a seat occupant for selectively providing input to the recliner apparatus 18 to control the movement of the upper seat assembly 20 with respect to the lower seat assembly 22.
  • the upper and lower 20,22 seat assembly is typically a frame like structure which provides a rigid support for the cushions which define the seat back and bottom 14,12 ( Figure 1).
  • the recliner apparatus 18 generally includes the upper seat assembly 20 pivotally attached to the lower seat assembly 22 at a pivot 24 and an actuator assembly 26.
  • the actuator assembly 26 is pivotally attached between the lower seat assembly 22 and the upper seat assembly 20 at a first pivot point 28 and a second pivot point 30 respectively.
  • the actuator assembly 26 is preferably attached in a substantially linear relationship with the upper seat assembly 20.
  • the actuator assembly 26 can be attached directly to the seat assembly 10, such as illustrated by the second pivot point 26 or can be attached through the use of a mounting bracket 32, such as illustrated by the first pivot point 30. Referring to the exploded view of Figure 3, more details regarding the actuator assembly 26 are provided.
  • a single ended reversible electric drive motor 34 is preferably provided.
  • the motor 34 includes a motor shaft 36 that rotates about its longitudinal axis.
  • a lamination and wire arrangement 38 and a collector 40 are supported for rotation with the shaft 36.
  • a magnet 42 and a stator 44 which also serves as a cover for the motor 34, effectively complete the electric motor portion.
  • a spindle member 52 includes a threaded elongated body portion and a gear member 54 at one end.
  • the gear member 54 interacts with a worm gear portion 56 at one end of the motor shaft 36.
  • the spindle member 52 and its associated gear member 54 are supported in the gearbox 48 and maintained in place by a clevis attaching member 58.
  • the interaction between the portion 56 on the motor shaft 36 and the gear member 54 provides for rotation along generally perpendicular axes. Specifically, as the motor shaft 36 rotates about its central axis, the spindle member 52 rotates about its central longitudinal axis. Accordingly, motor 34 activation causes selected rotation of the spindle member 52.
  • This perpendicular arrangement provides the ability to more easily fit the motor assembly in place beneath a seat within a vehicle.
  • a link member 60 preferably has a threaded interior surface that cooperates with the external threads on the spindle member 52.
  • the link member 60 is driven along the longitudinal axis of the spindle member 52 by the interaction between the external threads on the spindle member and the internal threads on the link member 60.
  • a spring washer 62 and a stop washer 64 preferably are positioned along the length of the spindle member 52 to provide an axial stop distal from the gear member 54.
  • the link member 60 is limited in its movement along the surface of the spindle 52 by the washer combination 62,64 at one end and by the interplay between the link member 60 and the gear housing 48 at the other end.
  • the spring washer 62 is included to provide a soft stop at the furthest position of the link member 60.
  • the gearbox 48 of the present invention provides an arrangement for mounting the drive motor 34 perpendicular to the link member 60.
  • the link member 60 is preferably in a substantially linear relationship with the upper seat assembly 20 when attached to the first pivot point 30.
  • the motor 34 can therefore be mounted along the lower seat assembly 22 while the link member directly actuates the reclined angle of the upper seat assembly 20.

Abstract

L'invention concerne un mécanisme électrique de positionnement de siège, permettant de régler automatiquement la position inclinée d'un dossier (14) dans un véhicule, à l'aide d'un seul moteur électrique (34). Un ensemble d'actionnement (26) est fixé rotatif à un ensemble de siège supérieur (20) et à un ensemble de siège inférieur (22), afin de produire une force motrice qui permet d'incliner sélectivement l'ensemble dudit siège supérieur par rapport à l'ensemble dudit siège inférieur. L'ensemble d'actionnement est fixé de manière sensiblement linéaire à l'ensemble de siège supérieur, et comprend de préférence un moteur d'entraînement réversible à une seule extrémité, et un agencement de boîte de vitesse. La boîte de vitesses offre un agencement permettant de monter le moteur d'entraînement perpendiculairement à l'ensemble de siège supérieur, afin d'obtenir un système d'inclinaison sûr, fiable, et stable qui n'est ni encombrant ni compliqué.
