Description

Title of the invention: Description Title: Slide for vehicle seat

[0001] The present disclosure relates to a slide for a vehicle seat which comprises a male profile and a female profile, sliding relative to each other, as well as a position sensor fixed to the male profile, configured to detect a movement of the male profile relative to the female profile.

[0002] The present disclosure further relates to a method of mounting a slide according to the present disclosure. Technical field

[0003] The present disclosure relates to the field of slides for vehicle seats comprising a female profile and a male profile mounted to slide relative to each other, and a position sensor fixed to the male profile, in an internal space of the slide. Prior art

[0004] A slide according to this state of the art is in particular known from document US 7,614,597 B2: The position sensor is fixed to the slide by a horizontal opening in a main wall of the male profile so as to position a detection part of the position sensor, internal to the slide, arranged between a male profile and a female profile of the slide, while a fixing part of the sensor comes to bear on the main wall of the male profile, on the outside, and comprises an external electrical connection. According to the inventors' findings, the position sensor projecting in the upper part of the male profile, and the electrical connection fixed at this level, represent obstacles offering a risk of snagging with the environment external to the slide.

[0005] Also known from document EP3456580, from the present Applicant, is a slide comprising a sensor housing fixed, like document US 7,614,597 B2, in an opening of a main wall of the male profile of the slide, and which therefore has the same drawbacks.

[0006] Also known from document FR3118610, from the present Applicant, is a seat slide whose position sensor housing is fixed to the male profile of the slide through a lateral opening, in a plane sensitive lateral wall of the male profile, opening through which extends an electrical connection, and therefore electrical cables connecting the position sensor. As can be understood from the figures of this prior art, such a sensor design is only compatible with certain slide designs, and in particular an asymmetric slide design. metric, which always guarantees the presence of free clearance so that the electrical connectors and electrical cables can always extend laterally, without risk of physical interference with the female profile, on this side.

[0007] Generally, there is a need for a sensor design for slides, in particular symmetrical profiles, allowing easy assembly of the position sensor to the slide, and limiting the risks of interference of the position sensor with the environment external to the slide. The present disclosure finds a particular application for compact slides in the vertical direction Z, for example with dimensions less than 35 mm such as 30 mm, between the main wall of the male profile and the base wall of the female profile.

[0027] [Fig.7] is a sectional view of the female profile, illustrating a substantially vertical wall of the female profile arranged in line with the detection window, configured to be detected by the position sensor, the wall being notched over a first length portion and solid over a second length portion, said position sensor in particular with magnetic operation configured to detect a change of state between the first length portion (notched) and the second length portion (not notched). Description of the embodiments

[0028] Also, the present disclosure relates to a slide 1 for a motor vehicle seat comprising a male profile 2, slidably mounted in a female profile 3, and a position sensor 4 fixed to the male profile 2 configured to detect a movement between the male profile 2 and the female profile 3.

[0029] The male profile 2, typically upper, movable relative to the female profile, is typically intended to be fixed to a frame of a seat base. Said male profile 2 comprises a main wall 20 extending longitudinally in a sliding direction X and transversely in a transverse direction Y along a horizontal plane, as well as a first lateral wall 21, on a first side of the main wall, extending in extension of the main wall 20 along a first vertical plane, as well as a second lateral wall 22, on a second side of the main wall, extending along a second vertical plane.

[0030] The first side wall is extended lower by a first male part 23 and the second side wall is extended by a second male part 24. The first male part and the second male part are typically directed outwards in the transverse direction Y. The male profile 2 has a lower, open mouth delimited at the base of the first side wall 21 and the second side wall 22, providing access to the hollow of the male profile, in particular along the length of the male profile 2.

[0031] The female profile 3, typically lower, comprises a base wall 30, intended to be fixed to the floor of a vehicle, said base wall 30 extending longitudinally in the sliding direction X and transversely along the transverse direction Y.

[0032] The base wall 30 extends: - on a first side, by a first female part 31, receiving the first male part 23, and forming with said first male part 23, at least one raceway CH1, CH2 between the first male part 23 and the first female part 31, and in particular a first raceway CH1, and a second raceway CH2 for balls, and - on a second side, by a second female part 32, receiving the second male part 24, and forming with the second male part, at least one raceway CH3, CH4, and in particular a third raceway CH3 and a fourth raceway CH4 for balls.

[0033] The position sensor 4 is fixed to the male profile 2, housed in an internal space E1 delimited between the male profile 2 and the female profile 3, said position sensor 4 configured to detect a displacement between the male profile 2 and the female profile 3 during the sliding of the slide. The detection sensor is configured to detect said displacement by detecting the female profile 3 through a detection window FD in the first side wall 21.

[0034] The detection window FD extends in the first side wall 21 of the male profile 2, and can be arranged inside the female profile 3, and as illustrated in [Fig.6]. The detection part of the position sensor 4 can be a magnetic sensor, said detection part configured to detect the presence of a portion of ferromagnetic wall of the female profile 3, substantially planar located opposite the window on the side of the window.

[0035] The wall PD of the female profile detected by the position sensor 4 may be a substantially vertical wall of the female profile arranged in line with the detection window FR, configured to be detected by the position sensor. 4

[0036] The detected wall PD may be notched over a first length portion L1 and solid over a second length portion L2 of the female profile, said position sensor, in particular magnetically operated, configured to detect a change of state between the first length portion L1 for which the notched wall of the female profile is not detected by the position sensor 4 and the second length portion L2 for which the wall PD (not notched) of the female profile is detected by the position sensor 4.

[0037] The position sensor 4 according to the present disclosure is configured to be inserted into the internal space E1 through the mouth at the base of the male profile and along a vertical insertion direction Z, perpendicular to the main wall 20 of the male profile.

[0038] When the position sensor 4 is inserted into the slide for which the male profile and the female profile can typically already be mounted to each other. In such a case, said insertion may require first sliding the male profile 2 relative to the female profile 3 into a relative position between the two profiles 2, 3 for which the female profile 3 does not obstruct the insertion of the position sensor 4 through the open mouth at the base of the male profile 2.

[0039] The position sensor 4 comprises a sensor body 40, as well as a spring locking system 41, mounted on the sensor body 40 configured to lock the position sensor 4 in a position in which the position sensor 4 is in said internal space E1, arranged in line with the detection window FD in the first side wall 21.

[0040] The sensor body 40 may comprise a typically plastic housing, for example molded, in particular by injection molding techniques. The spring locking system 41 may be a metal element, coupled to the sensor body, typically by elastic interlocking. The spring locking system 41 may typically be obtained by cutting, typically by stamping, and folding a spring metal sheet.

[0041] The spring locking system 41 comprises a first elastic part 410 configured to bear on the second side wall 22 by exerting a force in the transverse direction Y configured to keep the position sensor pressed by a stop surface 405 of said position sensor, in particular of the body of the sensor, against an internal face of the first side wall 21.

[0042] Generally speaking, and in particular as visible in [Fig. 6], the first elastic portion 410 which can take the form of an elastic curved blade is preferably inserted between the body of the sensor 40, and the second side wall 22. The first elastic portion 410 exerts a force on the body of the sensor 40 so that the stop surface 405 comes into contact with the internal face of the first side wall 21, in particular above the detection window. Positioning of the position sensor is ensured relative to the first side wall 21 in the transverse direction Y, and therefore relative to the wall PD of the female profile intended to be detected by the position sensor 4.

[0043] The spring locking system 41 further comprises a second elastic part 411 configured, during insertion of the position sensor 4 in the vertical direction Z, to deform elastically, during penetration of the second part elastic 411 into the detection window through a lower entrance of the detection window, before the second elastic part 41, deformed by the entrance (in particular compressed), returns elastically to lock against a locking notch ECVA; ECVB, on at least one lateral edge of the detection window.

[0044] Such a blocking in the second elastic part 411 against / in the locking notch ECVA, ECVB ensures the blocking of the sensor body 4 relative to the male profile in the vertical direction Z.

[0045] According to one embodiment, the second elastic part 411 may comprise a first elastic element 411a and a second elastic element 411b, with positions offset along the longitudinal direction X. The first elastic element 411a and the second elastic element 411b extend, along the transverse direction Y, overlapping one another, at the same distance as the first elastic part 410.

[0046] The first elastic element 411a and the second elastic element 411b are configured to engage with two guide edges Bda, Bdb converging (from bottom to top) along the vertical direction Z in the lower part of the detection window, at the level of said lower entrance during vertical insertion of the position sensor.

[0047] More particularly, the two guide edges are configured to engage respectively with the first elastic element 411a and the second elastic element 411b to elastically deform the second elastic part by bringing the first elastic element and second elastic element closer together, before an engagement of the first elastic element 411a in a first locking notch ECVA and an engagement of the second elastic element 411b in a second locking notch ECVB when the first elastic 411a and the second elastic 411b elastically move apart from each other, at the end of insertion of said position sensor into the male profile 2, after passage of the two guide edges Bda, Bdb.

[0048] According to one embodiment, the spring locking system 41 may advantageously be a single-piece metal element forming the first elastic part 410 and the second elastic part 411.

[0049] Said single-piece metal element may be obtained by stamping and folding a spring metal sheet. Said single-piece metal element may comprise two spring blades, forming the first elastic element 411a and the second elastic element 411b, adjoining by proximal ends of the spring blades to a central support 415 via folding lines typically extending in the transverse direction Y.

[0050] Said spring blades extend from the central support 415, following the transverse direction Y to the first side wall 21 where the spring blades engage respectively with the first ECVA locking notch and the second ECVB locking notch at their free distal end.

[0051] Generally speaking, the position sensor can be disassembled by pinching the free ends of the first and second elastic elements 411a, 411b in particular, of the spring blades in order to bring them together and in order to release them from the locking notches ECVA and ECVB, then by sliding the position sensor 4 downwards while keeping the two spring blades compressed in order to allow the sensor to be released.

[0052] The first elastic part 410 extends from the central support 415, in the transverse direction Y to the second side wall 22 and can take the form of a curved blade bearing on the second side wall 22 by a convex face of the curved blade.

[0053] Generally, the central support 415 may extend horizontally, parallel to a lower face of the sensor body 40, and the spring blades forming the first elastic element 411a and second elastic element 411b, arranged on either side of two lateral faces of the body of the housing, offset in the longitudinal direction X, and as visible for information purposes in [Fig. 2]. The two elastic blades may be divergent, in the transverse direction Y, from the central support 415, and in the direction of the first lateral wall 21, namely in the direction going from the second lateral wall 22 towards the first lateral wall 21.

[0054] Generally, the first elastic portion 410, on the one hand, and the second elastic portion 411, on the other hand, can be arranged, relative to the central support 415, on either side thereof, in the transverse direction Y.

[0055] Generally, the first elastic portion 410 may be said curved blade which extends from a proximal end secured to the central support 415 positioned under the housing, said curved blade extending in height covering a lateral surface of the housing opposite the second lateral wall 22, and in particular up to a free, upper end which comes to bear on the body of the housing at the height, or close to an upper surface of the housing.

[0056] The second coupling part 412 configured to cooperate by elastic interlocking with the first coupling part may be a projecting blade portion of the central support, in particular coplanar with the central support 415 forming a tooth configured to be elastically inserted into a cavity of the first torque part 401, on the lower surface of the sensor body 40.

[0057] Generally, the body 40 of the position sensor 4 may comprise a projecting portion 404 relative to the stop surface 405, in the transverse direction, fitting into the detection window FD. It is noted in particular that the upper edge of the detection window may comprise a centering notch ECC in which the projecting portion 404 of complementary shape to the ECC central notch.

[0058] Generally speaking, the interlocking cooperation between the detection window FD and the projecting portion 404 of the sensor body ensures that the position sensor 4 is aligned with the male profile in the direction X, longitudinal to the slide 1.

[0059] Preferably, the projecting portion 404 is preferably positioned flush with an external face of the first side wall 21. For this purpose, the projecting portion 404 projects from the abutment surface 405 substantially in the transverse direction Y, and in a dimension which is preferably close to the thickness of the first side wall 21, for example between 80% of the thickness and 120% of said thickness, such as 100%. It is preferably avoided that the body of the housing protrudes from the detection window FD. The fact that the projecting portion 404 is flush with the external wall of the first side wall 21 limits the risks of catching with the external environment.

[0060] Generally speaking, such a slide design finds a particular application for a compact slide, namely having an overall height marked “d” in [Fig.6], along the vertical direction Z between the main wall 20 and the base wall 30, preferably less than or equal to 35mm, such as 30mm. The slide may typically be a symmetrical slide, namely one whose male and female profiles have a plane of symmetry along a longitudinal axis of the slide.

[0061] The detection window FD is then typically located inside the female profile 3.

[0062] Preferably and for this purpose, the position sensor 4 is fixed near one of the two longitudinal ends of the male profile 2 and comprises an electrical connection 403, in particular female, internal to the male profile, said electrical connection 403 oriented towards said longitudinal end.

[0063] The electrical connection 403 is configured for the connection of an electrical plug electrically connected to an electrical cable emerging through a terminal mouth of the male profile. The terminal mouth of the male profile is delimited at the distal end of the male profile, between the main wall 20, on the one hand, and the first side wall 21 and the second side wall 22, on the other hand.

[0064] The present disclosure also relates to a vehicle seat comprising a slide according to the present disclosure, the male profile 2 of which is fixed to a seat base and the female profile 3 of which is fixed to a floor of the vehicle. The positions can however be reversed, namely that the male profile can be fixed to the floor and the female profile to said seat base.

[0065] The present disclosure further relates to a method of mounting a slide according to the present disclosure or belonging to a seat according to the present disclosure, comprising the provision of: - an upper, movable male profile 2, intended to be fixed to a frame of a seat base, said male profile comprising a main wall 20 extending longitudinally in a sliding direction X and transversely in a transverse direction Y along a horizontal plane, as well as a first lateral wall 21, on a first side of the main wall, extending in extension of the main wall 20 along a first vertical plane, as well as a second lateral wall 22, on a second side of the main wall, extending along a second vertical plane, and in which the first lateral wall is extended lower by a first male part 23 and in which the second lateral wall is extended by a second male part 24, the male profile having an open mouth at its base and, - a lower female profile 3, comprising a base wall 30, intended to be fixed to the floor of a vehicle, said base wall 30 extending longitudinally in the sliding direction X and transversely in the transverse direction Y, and in which said base wall 30 extends, on a first side, by a first female part 31, receiving the first male part 23, and forming with said first male part 23, at least one rolling path CH1, CH2 between the first male part 23 and the first female part 31, and on a second side, by a second female part 32, receiving the second male part 24, and forming with the second male part, at least one rolling path CH3, CH4, - a position sensor 4 configured to be inserted into the internal space El through the mouth at the base of the male profile and in a vertical insertion direction, perpendicular to the main wall 20 of the male profile, said position sensor 4 comprising a sensor body 40, as well as a spring locking system 41, mounted on the sensor body 40 configured to lock the position sensor 4 in a position in which the position sensor 4 is in said internal space El, arranged in line with the detection window FD in the first side wall 21.

[0066] The spring locking system 41 comprises a first elastic part 410 configured to bear on the second side wall 22 to keep the position sensor pressed against an internal face of the first side wall 21, in the transverse direction Y and a second elastic part 411 configured, during insertion of the position sensor 4 in the vertical direction Z to deform elastically, during penetration of the second elastic part into the detection window FD, before returning elastically to lock in a locking notch ECVA; ECVB, on at least one lateral edge of the detection window, ensuring the locking of the sensor body relative to the male profile in the vertical direction Z.

[0067] According to the method according to the present disclosure, the position sensor 4 is assembled to the slide by the following steps: - insertion of the sensor into the internal space El through the mouth at the base of the male profile and following a vertical insertion direction Z, perpendicular to the main wall 20 of the male profile, - locking of the position sensor, by deformation of the second elastic part 411 in engagement with an inlet of the detection window, during insertion of the position sensor 4 in the vertical direction Z, before said second elastic part returns elastically to lock in said at least one locking notch, and while said first elastic part 410 is configured to rest on the second side wall 22 to keep the position sensor pressed against an internal face of the first side wall 21, in the transverse direction Y

[0068] Once the position sensor is assembled, the position sensor is preferably fitted into the window by a projecting portion 404, in particular as previously defined, which ensures the position sensor is wedged relative to the male profile in the longitudinal direction X.

[0069] The position sensor 4 can be electrically connected by the electrical connector 403, which is oriented, in the direction X towards the terminal end of the male profile near which the position sensor 4 is fixed. A cable having a male electrical plug is passed through the terminal mouth of the male profile 2 delimited between the main wall 20, on the one hand, and the first side wall 21 and second side wall 22, on the other hand.
