Abstract: A walk-over seat has a base with a pair of side members and a seat back which may be moved between the front and rear ends of the seat. The seat back is connected to the upper ends of two elongated links on each side of the seat back. Each link has a lower end mounted for pivotal movement about a horizontal axis between frontwardly and rearwardly extending positions. Each link is engaged by a respective latching member when the link is in one of its positions. Structure is provided to transfer to the side members of the seat the load exerted against a latching member by the link when the seat back is impacted or hit from behind, to prevent the latching member from being sprung or bent out of position. The latching member has a special configuration to accommodate differing dispositions and mountings of the latching member and the link it engages.

Abstract: A tubular cylindrical portion of a connection terminal is held between upper and lower dies by pressure applied using a multi-purpose actuator lever. An end portion of a coated or insulated wire is held between an insert slider and a holder and is advanced toward an open end of the cylindrical portion of the connection terminal, through the use of an insert lever. The core wire is pressed into the cylindrical portion while its surrounding insulation is compressed and pushed back by engagement with the end portion of the cylindrical portion. The multi-purpose actuator lever is moved to crimp the cylindrical portion on the core wire. Then, the actuator lever is turned to separate the upper and lower dies. The wire is then withdrawn and the compressed insulation is moved to cover the cylindrical portion.
