Abstract

A seat complete measuring system (10) for measuring the efforts and range of travel of any movable component on a seat assembly (12) comprises a seat positioning station (24) for supporting and positioning the seat assembly (12). The seat positioning station (24) includes a planar support platform (26) for fixedly securing and supporting the seat assembly and an indexing mechanism supporting the support platform for rotating platform between one of a plurality of indexing positions. A multi-axis measuring station (46) is supported at a predetermined position adjacent the seat position station (24) for cooperating with the seat assembly (12). The multi-axis measuring station (46) includes a support platform (48) fixedly secured at the predetermined position adjacent the seat positioning station, a first measuring arm movable along an x-axis, a second measuring arm (50) movable along a y-axis, a third measuring arm (56) movable along a z-axis, and a tool arm movable along a rotation r-axis for supporting a tool adapted to engage one of the components of the seat. A controller (60) is operatively coupled to the seat positioning station and the multi-axis measuring station for controlling the stations and generating outputs of the measured efforts and range of travel of one of the movable components on the seat assembly during engagement and manipulation thereof by the multi-axis measuring station while supported and positioned by the seat positioning station in one of the indexing positions.

Claims

1. A measuring system for measuring the efforts and range of travel of one or more movable components on a seat assembly, said measuring system comprising:

a seat positioning station for supporting and positioning the seat assembly, said seat positioning station including a support platform for fixedly securing and supporting the seat assembly and an indexing mechanism supporting said support platform for rotating said support platform between one of a plurality of indexing positions;

a multi-axis measuring station supported at a predetermined position adjacent said seat positioning station for cooperating with the seat assembly supported and positioned by said seat positioning station in one of said indexing positions, said multi-axis measuring station including a support platform fixedly secured at said predetermined position adjacent said seat positioning station, a first measuring arm coupled to said support platform and movable along a first x-axis, a second measuring arm coupled to said first measuring arm and movable along a second y-axis, a third measuring arm coupled to said second measuring arm and movable along a third z-axis, and a tool arm coupled to said third measuring arm and movable along a rotational r-axis for supporting a tool adapted to engage one of the components of the seat; and

a controller operatively coupled to said seat positioning station and said multi-axis measuring station for controlling the movement of said stations and generating outputs of the measured efforts and range of travel of one of the movable components on the seat assembly during engagement and manipulation thereof by said multi-axis measuring station while supported and positioned by said seat positioning station in one of said indexing positions.

2. A complete measuring system as set forth in claim 1 further including a force sensor coupled to said tool arm for sensing the force required for moving one of the movable components on the seat assembly and a proximity sensor for sensing the range of motion of the movable component.

3. A complete measuring system as set forth in claim 2 wherein said indexing mechanism includes a housing for supporting a rotatable turntable connected to said support platform of said seat positioning station for rotating said seat positioning station between one of said indexing positions.

4. A complete measuring system as set forth in claim 3 wherein said indexing mechanism includes at least one proximity sensor adjacent said support platform of said seat positioning station for locating, identifying and defining said indexing positions upon rotation of said turntable.

5. A complete measuring system as set forth in claim 4 wherein said indexing mechanism includes a motor supported by said housing and coupled to said turntable for selectively rotation said turntable and said support platform between said indexing positions.

6. A complete measuring system as set forth in claim 5 wherein said support platform of said seat positioning station includes a plurality of coupling mounted thereto for receiving and securing the seat assembly to said support platform.

7. A complete measuring system as set forth in claim 6 wherein said first measuring arm includes a generally elongated and horizontal member slidably connected to said support platform of said multi-axis measuring station.

8. A complete measuring system as set forth in claim 7 wherein said second measuring arm includes a generally elongated and vertical member slidably connected to said first measuring arm.

9. A complete measuring system as set forth in claim 8 wherein said third measuring arm includes an elongated member slidably connected to and cantilevered from said second measuring arm and generally parallel to said first measuring arm.

10. A complete measuring system as set forth in claim 9 wherein said third measuring arm includes a distal end rotatably supporting said tool arm.

11. A complete measuring system as set forth in claim 10 further including at least one motor coupled between said multi-axis measuring station and said controller for automatically controlling and moving said measuring arms and said tool arm along said axes in response to said controller.
