  • This thus considerably strengthens the safety and ease of use of the massage head 1 and the device 2 objects of the invention, allowing in particular their use by an unqualified user (that is to say not having special knowledge in the field of massage).
  • the return member 14 can be of any known suitable type, and can for example comprise one or more helical tension or compression springs (" coil " springs), one or more helical torsion springs, one or more springs with blade(s), or a combination of these.
  • the return member 14 comprises a single helical torsion spring 15, one of the legs of which is positioned bearing against a surface of the frame 3 and the other of the legs is positioned bearing against a surface of the second means of support 12 of the second roller 5, and whose turns are wound around the third shaft which connects the second support means 12 to the frame 3.
  • other arrangements and configurations of the return member 14 could be retained, without however, going beyond the scope of the invention, to obtain the desired recall effect.
  • the tare of the return member 14, and in particular its return force is chosen, according to the intended application and the skin area to be treated, as a function of the resistance threshold of the skin.
  • the second roller 5 approaches the first roller 4 under the effect of the return member 14.
  • the return force of the return member 14 is on the contrary lower than the resistance force of the skin, so that the second roller 5 tends to move away from the first roller 4, its second axis d 'B-B extension' moving to its second position. This improves both the effectiveness and the comfort of the massage of the skin by the massage head 1, while guaranteeing the safety of use of the massage head 1 by an unqualified user.
  • the return member 14 is calibrated so that it exerts a return force from the second axis B-B', from its second position towards its first position, which is between 2 N and 20 N, and preferably again between 4 N and 10 N.
  • the torque of this helical spring 15 of torsion can advantageously be between 10 Nmm and 50 Nmm, even more advantageously between 20 and 40 Nmm.
  • Such calibration is in fact particularly well suited for the treatment, using the massage head 1, of an area of facial skin using the so-called “ palpate-roll ” technique mentioned previously.
  • the first and second positions of the second axis BB' of extension and rotation of the second roller 5 are stop positions, so as to mechanically limit, in a reliable and repeatable manner, the relative spacing range of the first and second rollers 4, 5.
  • said first and second positions are defined by fixed mechanical stops, defined once and for all during the design of the massage head 1. No particular adjustment is required. is thus required from the user.
  • the second position of the second axis BB' of the second roller 5 is defined by two fixed lateral stops 16A, 16B arranged at the level of the second support means 12 ( figures 1 And 2 ), and which come to bear against an external surface of the housing 3, which forms the frame 3 of the massage head 1, when the second axis BB' occupies its second position ( figures 5 And 6 ).
  • a single fixed stop could alternatively be considered.
  • the stops 16A, 16B are designed and dimensioned to ensure that the surface of the second roller 5 is maintained at a distance from the frame 3, so as to avoid any contact between the latter when the second axis BB' of rotation of the second roller 5 occupies its second position.
  • the first position of the second axis BB' of the second roller 5 can be defined, for example, by at least one fixed stop (and preferably two, not visible in the figures) arranged at the level of the second support means 12, and which comes to bear against a surface of the first support means 11 of the first roller 4 when the second axis BB' occupies its first position.
  • this fixed stop also makes it possible to avoid advantageously any interaction between the second support means 12 and the drive system housed within the housing 3.
  • said first and second positions could on the contrary be one and/or the other defined by adjustable mechanical stops (for example, screw), so that the user can define and adjust himself the value of the minimum E min and maximum E max spacing desired.
  • the massage head 1 can then be advantageously designed and configured so as to define a plane P 1 of contact of the first and second rollers 4, 5 with the skin which is oriented in a intersecting manner and not orthogonal to said fourth axis DD' of extension of the frame 3 of the massage head 1, and this, more preferably, whatever the (first or second) position occupied by the second axis BB' of extension and rotation of the second roller 5.
  • this plane P 1 of contact of the first and second rollers 4, 5 with the skin is intersecting and not orthogonal to the fourth axis DD' according to a minimum contact angle ⁇ min of at least 15°, when the second axis BB' occupies its first position, and at a maximum contact angle ⁇ max of 110° at most when the second axis BB' occupies its second position respectively.
  • ⁇ min minimum contact angle
  • ⁇ max maximum contact angle
  • the angle minimum contact angle ⁇ min could advantageously be chosen equal to 72.5°, while the maximum contact angle ⁇ max could advantageously be chosen equal to 91.5°.
  • the third pivot axis CC' of the second support means 12 of the second roller 5 relative to the frame 3 of the massage head 1 could be included in a plane containing the fourth axis DD' of extension of said frame 3, which contributes to the simplicity of design and the compactness of the massage head 1.
  • the system for adjusting the relative position of the first and second rollers 4, 5 can advantageously be designed and configured so as to define between, on the one hand a plane P 2 comprising the first axis AA' and the third axis CC' and, on the other hand a plane P 3 comprising the second axis BB' and the third axis C-C', a minimum opening angle ⁇ min between 95° and 110° (and preferably equal to 105°) when said second axis BB' occupies its first position, and a maximum opening angle ⁇ max between 135° and 150° (and preferably equal to 143°) when said second axis BB' respectively occupies said second position.
