An air bag provided with linear joined portions in the inflation section is disclosed. The linear joined portions linearly join the opposing wall portions of the inflation section. Each of the linear joined portions includes a body portion and end portions. The end portions extend from the body port

An air bag provided with linear joined portions in the inflation section is disclosed. The linear joined portions linearly join the opposing wall portions of the inflation section. Each of the linear joined portions includes a body portion and end portions. The end portions extend from the body portion and gradually become wider than the body portion. The periphery surrounds the end portions and is provided with at least three straight portions. This air bag restrains mesh spreading and inflating gas leakage from the vicinity of any of the end portions of the linear joined portions.

The clamp apparatus of claim 1 wherein said link mechanism is a wedge lock link mechanism. 3. The clamp apparatus of claim 1 wherein said link mechanism is a toggle link mechanism. 4. The clamp apparatus of claim 1 wherein said metal body is made of a material selected from at least one of the group consisting of an extruded metal and a machine formed metal. 5. The clamp apparatus of claim 1 wherein the unit assembly of piston, piston rod, floating head member, and link mechanism are assembled outside the metal body and then inserted into the metal body. 6. The clamp apparatus of claim 1 wherein the unit assembly also includes at least one track member which mates proximate with an upper end of the piston rod to guide same in its back and forth movement in said cavity. 7. The clamp apparatus of claim 1 wherein porting conduits are included near the bottom of the apparatus and proximate to a mid-point thereof, to provide for introduction of a pressurized fluid to both sides of said piston to effect back and forth movement thereof. 8. The clamp apparatus of claim 5 wherein said unit assembly is supported by said upper cap member for insertion of the unit assembly into the metal body. 9. The clamp apparatus of claim 6 wherein said floating head member once inserted into said cavity is held in a fixed position therein by attachment of said head member to said track member. 10. The clamp apparatus of claim 1 wherein roller bearings are included in the unit assembly proximate to a top end of said piston rod to facilitate release of the clamp arm from a locked condition. 11. The clamp apparatus of claim 1 wherein the upper cap member has an opening through which a position sensor is inserted into the interior of the metal body. 12. The clamp apparatus of claim 3 wherein said upper cap member is made of a high strength steel to take up more extensive load forces in the toggle link mechanism. 13. The clamp apparatus of claim 11 wherein said position sensor includes an angle of opening adjustment member which adjustment member can be moved to thereby adjust an angle of opening for the clamp arm. 14. The clamp apparatus of claim 1 wherein said metal body includes at least one T-slot on an exterior surface thereof to facilitate mounting of the clamp apparatus. 15. The clamp apparatus of claim 1 wherein a plurality of mounting holes are formed in the exterior of the metal body to facilitate mounting of the clamp apparatus. 16. The clamp apparatus of claim 1 wherein said drive shaft is mounted through the usage of steel bushings which are pressed into opposing sides of the metal body and metal bearings which are placed over a cross-section of the drive shaft. 17. A power clamp apparatus, comprised of, an extruded metal body with an interior cavity running there through; a unit assembly which is inserted into said interior cavity, and said unit assembly including; a piston for slidable back and forth movement within said cavity; a lower portion of said cavity acting as a chamber for said piston; a piston rod connected to said piston; a floating head member on the piston rod; a link mechanism connected proximate to an upper end of said piston rod; a lower cap member which closes off said cavity near a bottom end of said metal body; an upper cap member which clos
