https://en.m.wikipedia.org/wiki/G-suit https://en.m.wikipedia.org/wiki/G-suit I guess it's the same concept.

  That makes no sense, the point of pressurising a G-suit is to physically press on the pilot's lower body and drive blood towards the upper body, think adaptive high-pressure compression stocking. Pressurising the cabin can have no such effect. Plus the point of G-suit is high-G manoeuvres, not linear acceleration or deceleration: untrained humans can handle 17g eyeballs in and 12g eyeballs out for several minutes versus instants of 4~6 g along other axis, Stapp's work demonstrated that properly restrained humans could walk away from 46G eyeballs out (decelerating while facing forwards)

    But we actually may use a G-seats. You enter the seat, it wraps around you. It may break your neck on sudden deceleration though.

The only deceleration for which that'd happen is an explosive one where you'd dismantle the carriage into a wall (and even then it's unlikely to break your neck), and a broken neck would be the least of your worries.
