A vehicle includes a frame. The vehicle is an open-frame vehicle. The frame includes an A-pillar, a B-pillar, and a roof siderail. The roof siderail extends between the A-pillar and the B-pillar. An A-pillar trim member is coupled to the A-pillar and includes a first portion and a second portion. The first portion defines an aperture that receives the second portion. A B-pillar trim member is coupled to the B-pillar. A roof siderail trim member is coupled to the roof siderail and extends between the A-pillar trim member and the B-pillar trim member. An inflatable member is positioned between the frame and at least two of the A-pillar trim member, the B-pillar trim member, and the roof siderail trim member when the inflatable member is in a deflated state. An inflated state of the inflatable member separates the second portion of the A-pillar trim member from the aperture of the A-pillar trim member.
