摘要： The headrest is adjustably mounted by a molded plastic guide inserted through an aperture of the mounting bracket concealed in the seat back and having a tubular body with a central bore therethrough for receiving the support post of the headrest. Flexure fingers are molded integrally with the tubular body and have a free state radially contracted position partly obstructing the central bore. One or more locking abutments are provided on the outside of the flexure fingers and are radially contracted therewith to facilitate insertion of the tubular guide through the mounting bracket aperture. Upon insertion of the headrest post the flexure fingers are forced radially outward to lock the locking abutments with the mounting bracket. The forced radial outward flexure of the flexure fingers induces a radial inward bias by which the flexure fingers frictionally engage and maintain the support post at a selected vertically adjusted position relative the seat back. The support post has a necked down central portion defining a stop face. A flange molded integrally with the plastic guide overlies the top of the seat back and defines a recess opening which cages a retainer spring seating within the necked down central portion for engagement by the stop face to limit the adjusting movement of the headrest.

摘要： A headrest for a vehicle seat wherein the cushioned headrest pad has one or more vertically depending support arms thereon which are vertically slideable in support brackets mounted within the seat cushion. Each support bracket is formed with a guideway for receiving the associated support arm. Each support bracket has a pair of inclined tabs thereon, an upper tab inclining upwardly and away from the guideway and a lower tab inclining downwardly and away from the guideway to form with an axially extending surface portion of the support arm a pair of acute angle cavities. Cylindrical members are arranged in the cavities to form friction wedges and springs are connected with the cylindrical members to urge them into tangential contact with the tabs and with the support arm so that vertical movement of the support arm is yieldably resisted by the frictional wedge action of spring-biased cylindrical members.

摘要： A headrest is mounted to a seat back by inserting a support into a support hole of a holder and inserting a stay of the headrest into to stay hole of the support inserted into the support hole of the holder. A gap occupying part provided in the support moves between an advanced position at which the gap occupying part protrudes from an outer wall of the support and is capable of touching an inner surface of the support hole, and a retracted position at which the gap occupying part is retracted to an inner side of the stay hole from the advanced position. The gap occupying part moves toward the retracted position from the advanced position when the support is inserted into the support hole, and moves toward the advanced position when the stay is inserted into the stay hole.

摘要： A child's safety seat comprises a seat body having a seat portion, a back rest and vertically extending side walls projecting forwardly from the side edges of the back rest. First and second guide means adjacent to the junction between the seat portion and the back rest for serve to locate a lap portion of an adult seat belt. A head rest is mounted on the back rest by means permitting adjustment of the distance between the head rest and the seat portion. Third guide means is positioned so as to guide a shoulder portion of an adult belt between the back rest and the head rest.

摘要： A headrest mounting structure to be provided in seats for vehicles such as automobiles is disclosed in which two spaced stays for supporting a headrest onto a seat back are respectively inserted into two support tubes provided in the seat back and the two support tubes are respectively inserted through a pair of brackets fixed to the seat back. Each of insertion bores formed in the brackets for insertion of the support tubes and insertion bores formed in the support tubes for insertion of the stays is formed as an elongated bore having a straight portion extending transversely of the seat back. Such elongated insertion bores permit compensation of errors in the distances between the stays as well as between the support tubes.

摘要： The headrest is adjustably mounted by a molded plastic guide inserted through an aperture in the mounting bracket concealed in the seat back and having a central bore for receiving a support post of the headrest. Longitudinally extending slots communicate with the central bore to define a plurality of circumferentially spaced radially yieldable flexure fingers. An abutment is carried by at least one of the flexure fingers and includes a ramp which momentarily deflects the flexure finger radially inward upon insertion of the plastic guide through the mounting bracket aperture and a shoulder which engages with the mounting bracket to retain the plastic guide in the mounting bracket. A spring bears radially inward upon at least one of the flexure fingers to urge frictional engagement with the support post and establish the support post at a desired vertically adjusted position. The support post has a necked down central portion defining an upwardly facing stop face. A flange molded integrally with the plastic guide overlies the top of the seat back and defines a recess opening which cages a retainer spring seating within the necked down central portion of the support post for engagement by the upward facing stop face to limit the upward adjusting movement of the headrest.
