SUPPORT ASSEMBLY FOR A VEHICLE

A vehicle includes a first pillar and a second pillar. The first pillar is spaced from and opposite the second pillar to define a gap therebetween. At least one seatback is positioned between the first pillar and the second pillar. A support assembly spans the gap and operably couples the at least one seatback with the first and second pillars. The support assembly includes a first support member operably coupled to the first and second pillars and a second support member telescopically connected with the first support member.
