Coupling mechanism and slide rail assembly with cushioning function

A coupling mechanism adapted for a furniture part and a slide rail, the coupling mechanism comprising:

• a first base, the first base being configured for detachably engaging the slide rail;
• a second base displaceably connected to the first base and being adapted for attachment to the slide rail, the second base further being adapted for attachment with the furniture part;
• a coupling base detachably coupled to the first base, the coupling base including a main portion configured to slidably engage the slide rail along a longitudinal direction, and an elastic portion extending transversely from the main portion relative to the longitudinal direction, the elastic portion being configured for releasably locked coupling with the first base, the elastic portion having an engaging section formed with a serrated contour and the first base having an engaging structure formed with a serrated contour corresponding to the serrated contour of the engaging section, the serrated contour of the engaging section projecting transversely from the elastic portion relative to the longitudinal direction;
• and
• a cushioning structure deflectively captured between the second base and the coupling base, the cushioning structure having a winding contour extending longitudinally from the coupling base and being deflected between the second and coupling bases to elastically maintain contact therebetween in correspondence with a change in a gap between the first base and the slide rail.
