Abstract
The invention proposes a connecting element (5) with an elongated shaft (19), in particular a screw or bolt, for connecting two bodies, wherein at least part of the shaft (19) has a slot (14) and a recess (13). The invention also proposes that a component (10) that generates a magnetic field, and spaced apart from it, a magnetically sensitive element (11) be disposed in the vicinity of the recess (13). The proposed connecting element is particularly suitable for detecting a force or mechanical strain acting on the seat of a motor vehicle.
Claims14
A connecting element, in particular a screw or bolt, with an elongated shaft (19), characterized in that at least part of the shaft (19) has a slot (14) and a recess (13), wherein a component (10) that generates a magnetic field and spaced apart from it, a magnetically sensitive element (11) are disposed in the vicinity of the recess (13).
The connecting element according to one of the preceding claims, characterized in that the shaft (19) is connected to a head (18).
The connecting element according to one of the preceding claims, characterized in that the recess (13) is let into the shaft (19) at the end of the shaft (19) oriented away from the head (18).
The connecting element according to one of the preceding claims, characterized in that the recess (13) and the slot (14) are let into the shaft (19) in such a way that the shaft (19) is divided into a first part (16) and a second part (17), which are separated from each other by the slot (14), and wherein one of the two parts (16, 17) has the recess (13) at its end oriented away from the head (18).
The connecting element according to one of the preceding claims, characterized in that one of the two parts (16, 17) of the shaft (19) is connected to the component (10) that generates the magnetic field and the other part (16, 17) is connected to the magnetically sensitive element (11).
The connecting element according to one of the preceding claims, characterized in that in particular, the component (10) that generates the magnetic field is a platelike permanent magnet connected to the shaft (19).
The connecting element according to one of the preceding claims, characterized in that the magnetically sensitive element (11) is a Hall sensor element, which is connected to the shaft (19) and is in particular disposed on a support (12).
The connecting element according to one of the preceding claims, characterized in that in the vicinity of the connection of the shaft (19) to the head (18), a bore (15) is let into the head (18) and/or into the shaft (19) and is connected to the slot (14).
The connecting element according to one of the preceding claims, characterized in that functioning as an imaginary plane of symmetry, the slot (14) divides the connecting element (5), with the exception of the recess (13), into two equal parts (16, 17) that are connected to each other by means of the head (18).
The connecting element according to one of the preceding claims, characterized in that a strain gauge is additionally provided in a certain region and can also detect a force or mechanical strain acting on the connecting element (5).
The connecting element according to one of the preceding claims, characterized in that it is embodied as a screw, bolt, socket pin, or rivet for connecting two bodies.
A use of a connecting element according to one of the preceding claims for detecting a force or mechanical strain acting on a seat of a motor vehicle.
