Abstract: According to an aspect of the present invention, a headrest apparatus for a vehicle seat includes a support portion mounted on the vehicle seat, a movable portion supported at the support portion for moving forward, a first arm and a second arm being crossed and rotatably connected each other by a rotation axis and supporting the movable portion to the support portion, and a biasing member provided between the support portion and the movable portion for biasing the movable portion forward relative to the support portion.

Abstract: A seat with a massage mechanism includes recessed sections at flanges on opposite sides of a base frame. Screw-nut mechanisms are arranged along the opposite sides, in which brackets are fixed to nuts and a rod is held by links supported by the brackets. The rod includes push rollers. The rod moves vertically along guide sections and is retracted in the recessed sections. In the recessed sections, the rod and the push rollers do not receive the weight of a sitter.

Abstract: A lumbar support device for a vehicle seat is comprised a seat back frame comprising the side frames and an upper frame connecting an upper portion of each side frame, a spring member, and a support body supporting a part of the spring member so as to be movable in front and back directions relative to the seat back by a drive device. The lumbar support device also includes a retracting restriction mechanism disposed between the support body and the drive device or between the support body and the spring member to prevent the spring member from moving backward relative to the seat back when a load applied to the spring member is equal to or more than a predetermined value.

Abstract: A paint for forming a heat absorbing film which exhibits a good binding property for binding with a conductive reflecting film, contains a black pigment, and a compound represented by Si(OR1)nR2m, where n+m=4, n=1 to 4, m=0 to 3, each of R1 and R2 is one of an alkyl group, an alkenyl group and an aryl group, or a hydrolyzate of the compound. Also, the present invention relates to a heat absorbing film formed out of this heat absorbing film paint and a color CRT provided with this heat absorbing film.

Abstract: A headrest device includes a thinner and improved positioning of the vertical position adjusting device. A geared or threaded drive shaft and a guide are positioned parallel to each other and parallel relative to a backrest. The driving force is directly transmitted from a motor unit positioned at the upper portion of the drive shaft and the guide to the drive shaft without a gear cable. The motor unit is directly assembled between a pair of longitudinal stay shaft portions at the upper portion of a seat backrest frame without a bracket.

Abstract: A head rest device for a vehicle seat includes a stay member supporting a head rest and attached to the upper portion of the seat back of the vehicle seat. The stay member includes a pair of stay shafts extending downwardly from the head rest. The head rest device further includes a position adjusting mechanism for adjusting the position of the head rest relative to the seat back. The position adjusting mechanism includes a drive motor, a drive shaft operatively connected to the drive motor and extending in the vertical direction of the vehicle, a vertically movable nut member in engagement with the drive shaft, a movable member secured to the nut member and vertically movable with the nut member, a guide member for guiding the vertical movement of the movable member, and a stopper member connecting the movable member with the lower end of the stay shafts of the stay member for restricting the position of the movable member.

Abstract: A lock mechanism which is capable of selecting a locked state or an unlocked state with respect to a seat fixing member is disposed on a rear leg portion of a seat. A hook portion is formed at each of a front portion and a rear portion of an opening portion of a notch formed in a front leg portion of the seat. A projection of a base hook which is swingably connected to the front leg portion is engageable with an engaging projection of a cam that is swingably connected to the front leg portion. The cam is engaged with a spring for urging the cam in a direction in which the engaging projection engages with the projection. Due to a hook portion of the front leg portion passing beneath a pin which is disposed in a rail and which has reached a bottom of a groove in the base hook, the seat and the pin are prevented from becoming disengaged from each other.

Abstract: A headrest apparatus for a vehicle seat. The seat has a seat cushion and a seat-back to support the back of a user of the seat. The headrest apparatus has a holder on a top portion of the seat-back; a stay having first and second supporting portions in parallel, the holder holding the stay so that the stay can slide relative to the seat back along the direction of the seat back; and a headrest body attached to the stay. The first stay includes a plurality of first notches for maintaining the position of the headrest body, the plurality of first notches defining an adjusting area of the headrest body. The second stay includes at least one second notch, the second notch defining a storage area of the headrest body different from the adjusting area. The operator can lower the headrest into the storage area even if the vehicle seat is a rear seat. This improves the operator's field of vision when necessary.

Abstract: A medical suturing material which is loaded into an automatic suturing device having a staple line when used. The medical suturing material according to the present invention is formed into a bag shape having a closed leading end by sewing a sheet shape suturing material by using a suturing thread. The main material of the suturing material is unwoven fabric such as felt, woven fabric or a knit cloth having somewhat flexibility and stretchability. In particular, bioabsorbable polymer, such as polyglycolic acid or a portion of a tissue of an organism is employed. Since the suturing material according to the present invention is formed into the bag shape having a closed leading end by sewing, displacement taking place attributable to shrinkage in the insertion direction can be prevented when the automatic suturing device is inserted.
