POSITION SIGNALING DEVICE
First Claim
1. Position signaling device for detecting a position of two metallic or metal-coated components that can move relative to one another, comprising:
- a magnetic field-sensitive sensor and at least one bias magnet that are spatially separated from one another and that are arranged stationary relative to one another and on two sides border a receiving gap, in which one of the two components can be moved relative to the other, the magnetic field-sensitive sensor and the bias magnet being connected to one of the two components, wherein in a vicinity of at least one of the magnetic field-sensitive sensor and the at least one bias magnet, at least one flux concentrator is arranged such that a substantially closed magnetic circuit is formed.

Abstract
A position signaling device is disclosed for detecting a position of two metallic or metal-coated components that can move relative to one another. the device can include a magnetic field-sensitive sensor and at least one bias magnet that are spatially separated from one another and are arranged in a stationary manner relative to one another. The magnetic field-sensitive sensor and the bias magnet on two sides border a receiving gap in which one of the two components can be moved relative to the other. The magnetic field-sensitive sensor and the bias magnet are connected to one of the two components. In a vicinity of the magnetic field-sensitive sensor and/or of at least one bias magnet, at least one flux concentrator is arranged such that a largely closed magnetic circuit is formed.

16. A vehicle seat comprising:
-
a movable seat rail for movement relative to a mounting rail; a vehicle position signaling device connected to the mounting rail for detection of a displacement position of the vehicle seat, the positioning signaling device including; a magnetic field-sensitive sensor and at least one bias magnet that are spatially separated from one another and that are arranged stationary relative to one another and on two sides border a receiving gap, in which one of the two components can be moved relative to the other, the magnetic field-sensitive sensor and the bias magnet being connected to one of the two components, wherein in a vicinity of at least one of the magnetic field-sensitive sensor and the at least one bias magnet, at least one flux concentrator is arranged such that a substantially closed magnetic circuit is formed, wherein the magnetic field-sensitive sensor, the at least one bias magnet, and the flux concentrator are mounted on one of the movable seat rail and the mounting rail, and an interrogation sheet is mounted on the other of the movable seat rail and the mounting coil and projects into the receiving gap between the magnetic field-sensitive sensor and the at least one bias magnet to influence a magnetic field of the bias magnet when the vehicle seat moves. - View Dependent Claims (17)
