Abstract: A device for supporting a human body in a lying-down position, notably in a prone position, is made up of at least one shoulder support module and at least one pelvis support module. The shoulder support module and the pelvis support module are made up of a first portion that comes into contact with the human body, the first portions forming a pneumatic cavity having a valve, and the first portion of the shoulder support module being kept at a pressure of less than 0.04 bar underneath the weight of the human body.

Abstract: A tire is provided with a tread that includes first and second sectors and grooves. The second sectors are formed of a rigid reinforcing compound. Each of the first and second sectors has a contact face intended to contact a road surface when the tire is in use. Each groove includes sidewalls and a bottom, and extends from an end of an adjacent contact face. A depth P of each groove is measured in a radial direction between its bottom and a position corresponding to a radial height of the adjacent contact face. At least one of the second sectors has a contact face that includes a recess having a depth p of less than 2 mm, as measured in a radial direction from a surface of the recess to a position corresponding to a radial height of an adjacent first sector.

Abstract: A device for supporting a part of a human body is made up of a first element forming a pneumatic cavity having a valve, the pneumatic cavity being kept at a pressure of less than 0.04 bar under load and at least the surface of the at least one first element that comes into contact with the part of a human body is covered by a “3D spacer” fabric.
