Abstract
The present disclosure relates to a modular seat bottom cushion, configured to be attached to a seat structure having a seat bottom structure comprising two lateral flanges spaced apart by a front transverse tube and a rear transverse tube, the modular seat bottom cushion comprising, in the assembled state: a base comprising a mechanical interface system for attachment to the seat bottom structure, padding resting on an upper surface of the base a covering which covers the padding.
Claims19
A modular seat bottom cushion, configured to be attached to a seat structure having a seat bottom structure comprising two lateral flanges spaced apart by a front transverse tube and a rear transverse tube, the modular seat bottom cushion comprising, in the assembled state:
- a base, comprising a mechanical interface system for attachment to the seat bottom structure,
- a padding resting on an upper surface of the base,
- a covering which covers the padding, and wherein the mechanical interface system comprises:
- a rear mechanical interface on a rear part of the base, comprising a first open recess, configured to house the rear tube, pivotably around the rear tube,
- a front mechanical interface, on a front part of the base, comprising a second open recess, configured to house the front tube in a mechanically lockable manner via a locking system of the front mechanical interface,
- and wherein the mechanical interface system is configured to allow the attachment of the modular seat bottom cushion by the following steps:
- a. placing the rear mechanical interface opposite the rear tube and inserting the rear tube into the first recess, and
- b. pivoting the modular cushion around the rear tube then fitted into the first U-shaped recess of the rear mechanical interface until the front tube is inserted into the second recess of the front mechanical interface and mechanically locking the front tube in the second recess via the system for locking the front mechanical interface, and
- wherein the first recess is a U-shaped open recess, and
- wherein the first U-shaped recess opens toward the rear of the base in a rear direction oriented from the front portion toward the rear portion of the base, the first U-shaped recess having an upper side wall and an opposite lower side wall, as well as a bottom wall, the U-shaped recess being configured so as to provide that the rear tube is held stably against the bottom wall when the base exerts a force on the rear tube directed in the rear direction, the rear tube then being blocked in a direction perpendicular to the base between the upper side wall and the lower side wall.

- a. placing the rear mechanical interface opposite the rear tube and inserting the rear tube into the first recess, and
- b. pivoting the modular cushion around the rear tube then fitted into the first U-shaped recess of the rear mechanical interface until the front tube is inserted into the second recess of the front mechanical interface and mechanically locking the front tube in the second recess via the system for locking the front mechanical interface
- and wherein the locking system of the front mechanical interface comprises a locking member, articulated by a flexible hinge, at a proximal end to the body of the base relative to the second recess and having a locking tooth at its distal end, as well as a cam secured to the locking member, and wherein the locking member is configured to switch from an unlocked position, leaving the second recess open, to a locked position, closing the second recess, so that in step b the front tube engages the cam, during its insertion into the second recess, by causing the locking member to move around the hinge from the unlocked position to the locked position during which the locking member is elastically deformed by passing a counter-tooth of the mechanical interface, secured to the base, and to the locked position for which the locking member is at least partially relaxed in a position where the locking tooth and the counter-tooth cooperate to prevent the unlocking of the locking member in a position where the locking member holds the front tube captive in the second recess.
