The present invention relates to a battery comprising a crosslinked intumescent layer selected from a coating and a self-supported film or sheet the layer being formed from a curable intumescent composition comprising: (a) a resin component comprising one or more oligomeric or polymeric compounds having a plurality of functional groups; (b) optionally a curing agent having a plurality of functional groups that are reactive with the functional groups of the oligomeric or polymeric compound of resin component (a); and (c) a compound providing an expansion gas upon thermal decomposition; wherein compounds (a) to (c) differ from each other, to an article comprising a battery, wherein the crosslinked intumescent layer is applied to a part of the article adjacent to the battery between the battery and the article, to methods to provide fire protection to a battery or an article comprising a battery or to reduce or prevent thermal runaway of a battery.

An assembling structure of a vehicle body may include side sill members provided in a length direction of a vehicle at both side portions of a lower portion of the vehicle body, respectively, a dash cross member provided in a width direction of the vehicle, both side end portions thereof being assembled to front end portions of the side sill members, center members provided in the length direction of the vehicle between the side sill members and a central portion of the vehicle body, front end portions thereof being assembled to a lower end portion of the dash cross member, and reinforcing members provided in the width direction of the vehicle between the center members and the side sill members, a first end portion of each reinforcing members being assembled to the center members and a second end portion of each reinforcing members being assembled to the side sill members.

A vehicle includes a frame, at least two front wheels and at least two rear wheels operatively connected thereto, and a motor operatively connected to the wheels. A cockpit area includes a cockpit floor extending between a left end and a right end. A roll cage connected to the frame is disposed at least in part over the cockpit area. A driver seat connected to the frame and disposed in the cockpit area includes a driver seat base. A passenger seat connected to the frame and disposed in the cockpit area includes a passenger seat base. The passenger seat is disposed side-by-side with the driver seat. A storage space is defined at least in part by the cockpit floor and the driver seat base. The storage space is disposed under the driver seat base, and extends continuously laterally between the left end and the right end of the cockpit floor.

To sufficiently improve the distortion stiffness of a vehicle body in a case in which no floor tunnel largely bulging upward from a floor panel is provided. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger is to sit, a cross member provided at a rear portion of the floor panel and extending in a vehicle width direction, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction, and a connecting member connecting the cross member and a rear portion of the center frame.

To decrease the retraction amount of a traveling motor at front collision. A vehicle-body structure includes a floor panel constituting a floor of an occupant space including a seat on which a passenger sits, a center frame disposed to be higher than and away from the floor panel at a vehicle-width-direction central portion of the occupant space and extending in a vehicle front-rear direction, and a connecting member extending upward from the floor panel, having an upper portion fixed to the center frame, and connecting the center frame to the floor panel. A traveling motor is arranged on a vehicle front side of the connecting member.

In an embodiment, a vehicle body structure includes a dash cross member disposed on an upper surface of a dash floor in a lateral direction of a vehicle. A lower side member is coupled to a lower side of the dash floor to face the dash cross member and coupled to a side wall of a side sill. A body mounting bracket is provided under the lower side member and coupled to a frame.

A vehicle body front section structure has a floor tunnel that projects into a vehicle interior on an underfloor of a vehicle, that is formed in a vehicle longitudinal direction, and that has a floor tunnel front end part disposed at a vehicle front of the floor tunnel, and floor tunnel members, a front end ridge line part, a first vehicle body front section reinforcing member that covers, from an outside of the vehicle, a whole of the floor tunnel front end part, from a vehicle upper end to a root of each of the floor tunnel members, and that is provided in the vehicle longitudinal direction along the front end ridge line part, and front side members, each of which has a lower end root that is connected to a dash panel, and each of which extends forward from the lower end root.

There is provided a vehicle lower section structure including a rocker that extends in a vehicle front-rear direction at a vehicle width direction outer side, a tunnel section that extends in the vehicle front-rear direction at a central portion in the vehicle width direction, a pair of dash cross members that extend in the vehicle width direction at a lower side of a dash panel, that are separated by the tunnel section, tunnel reinforcement that is disposed at a lower side in the vehicle up-down direction that extends in the vehicle front-rear direction, wherein a first front flange is formed at a front end of the dash cross member in the vehicle front-rear direction, and wherein a second front flange is disposed at a position opposing the first front flange across the dash panel or a floor section.
