Modular squab cushion, and seat assembly comprising such a cushion

A modular squab cushion, configured to be attached to a seat structure having a squab structure comprising two lateral flanges spaced apart by a front transverse tube and a rear transverse tube,

• the modular squab cushion comprising, in the assembled state:
• a support forming a base comprising a mechanical interface system for attachment to the squab structure,
• the padding resting on an upper surface of the support,
• and wherein the mechanical interface system comprises:
• a rear mechanical interface, on a rear portion of the support, comprising a first, open housing, configured to accommodate the rear tube in a mechanically lockable manner by a locking system, in particular of the rear mechanical interface and/or external to the rear mechanical interface, or even external to the modular squab cushion,
• a front mechanical interface on a front part of the support, comprising a second open housing, configured to house the front tube, pivotably around the front tube,
• and wherein the mechanical interface system is configured to allow the attachment of the modular squab cushion by the following steps:
• /A2/ placing the front mechanical interface opposite the front tube and inserting the front tube into the second housing and
• /B2/ pivoting the trim support around the front tube fitted into the second housing of the front mechanical interface until the rear tube is inserted into the first housing of the rear mechanical interface and mechanically locking the rear tube in the first housing via the locking system.
