上記特許文献2には、尻載せ用の円板状クッション部に着座した状態でもシートクッションをドア開口部に向けて自由に回転できて身体が不自由な人でも負担なく楽に乗り降りするができる、と記載されている。   In Patent Document 2 described above, even in a state where the seat cushion is seated on a disk-shaped cushion portion for placing on the hips, the seat cushion can be freely rotated toward the door opening, and even a person with a physical disability can easily get on and off without burden. It is described.

しかし、上記車両用シートでは、尻載せ用の円板状クッション部の周囲部分が固定されているから、座った人が回転すると膝の裏が前記周囲部分に擦れるため、スムーズに回転することができず、擦れないようにするには回転時に足を持ち上げた姿勢を保持する必要がある。   However, in the above-mentioned vehicle seat, since the peripheral portion of the disk-shaped cushion portion for mounting on the hips is fixed, when the seated person rotates, the back of the knee rubs against the peripheral portion, so that it can rotate smoothly. It is necessary to maintain a posture in which the foot is lifted during rotation in order to prevent it from being rubbed.

このように本実施例では、回動部33のロック機構80を備えるから、着座位置と回動位置で回動部33をロックでき、乗り降りなどを安定して行うことができる。   As described above, in the present embodiment, since the lock mechanism 80 for the rotating portion 33 is provided, the rotating portion 33 can be locked at the sitting position and the rotating position, and the getting on and off can be performed stably.

図11は本発明の実施例5を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述する。この例では、クッションユニット31を備えた車両用シート1に装備する装備品を示す。   FIG. 11 shows a fifth embodiment of the present invention, in which the same parts as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted. In this example, equipment to be mounted on the vehicle seat 1 having the cushion unit 31 is shown.

装備品として、前記回転位置において、前記回動部33の回動を規制する規制部を備え、前記回動部33の外周に突起状のストッパ85を設け、このストッパ85が前記回動位置で前記段差面35の端部35Tに当接して回動部33の回動を規制する。尚、前記ストッパ85が回動部側規制部であり、前記端部35Tが固定部側規制部である。   As the equipment, a regulating portion for regulating the rotation of the rotating portion 33 is provided at the rotating position, and a stopper 85 having a protruding shape is provided on the outer periphery of the rotating portion 33. The rotation of the rotating portion 33 is restricted by contacting the end 35T of the step surface 35. Note that the stopper 85 is a rotation-portion-side regulation portion, and the end portion 35T is a fixed-portion-side regulation portion.

そして、着座した姿勢で、回動部33を回すと、ストッパ85が端部35Tに当接してそれ以上回転することがなく、回動部33が回動位置に位置決めされ、この位置でロック機構80を操作してロックすることができる。尚、前記端部35Tが固定部側固定部である。   When the rotating portion 33 is rotated in the seated position, the stopper 85 contacts the end portion 35T and does not rotate any more, and the rotating portion 33 is positioned at the rotating position. 80 can be locked by operating it. The end 35T is a fixed part side fixed part.

このように本実施例では、対向面たる段差面35の車両の幅方向のドア側寄りには、ストッパ85に係合して回動部33の回動を規制する規制部たる端部35Tが設けられているから、回動部33の回動方向を規制することができる。   As described above, in the present embodiment, the end portion 35 </ b> T serving as a restricting portion that engages with the stopper 85 and restricts the rotation of the rotating portion 33 is provided near the step surface 35, which is the opposing surface, in the width direction of the vehicle. Since it is provided, the rotating direction of the rotating portion 33 can be regulated.

図12は本発明の実施例6を示し、上記各実施例と同一部分に同一符号を付し、その詳細な説明を省略して詳述する。この例では、クッションユニット31を備えた車両用シート1に装備する装備品を示す。   FIG. 12 shows a sixth embodiment of the present invention, in which the same parts as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof will be omitted. In this example, equipment to be mounted on the vehicle seat 1 having the cushion unit 31 is shown.

前記回動部33を前記回動位置から着座位置に復帰させる復帰手段86を備え、この復帰手段86としてバネなどの付勢手段を用いることができる。この例では、前記復帰手段86は、前記軸部材64に外装したコイルスプリングからなるトーションバネ87を備え、このトーションバネ87の一側端部88を、前記回動部33に固定した鍔部65に連結部89により連結し、そのトーションバネ87の他側端部88を、前記固定部32に固定した鍔部65に連結部89Aにより連結している。   There is provided a return means 86 for returning the rotation part 33 from the rotation position to the seating position. As the return means 86, an urging means such as a spring can be used. In this example, the return means 86 includes a torsion spring 87 formed of a coil spring provided on the shaft member 64, and a side end 88 of the torsion spring 87 is fixed to a flange 65 fixed to the rotating portion 33. The other end 88 of the torsion spring 87 is connected to the flange 65 fixed to the fixing portion 32 by a connecting portion 89A.

そして、トーションバネ87は、前記着座位置で直線部55Bが固定部32の直線部35Bに当接する方向に回転するように回動部33を回動付勢しており、回動部33を回動位置に回すと、端部88,88同士が近付くように弾性変形し、これにより弾性復元力が増加し、トーションバネ87により、回動部33が着座位置側に回転させるように付勢される。   The torsion spring 87 urges the rotating portion 33 so that the linear portion 55B rotates in a direction in which the linear portion 55B contacts the linear portion 35B of the fixed portion 32 at the seating position. When turned to the movement position, the ends 88, 88 are elastically deformed so as to approach each other, thereby increasing the elastic restoring force. The torsion spring 87 urges the rotating portion 33 to rotate toward the seating position. You.

従って、回動位置まで回動部33を回した後、着座者が降り、ロックを解除すると、回動部33がトーションバネ87の付勢により着座位置に復帰し、或いは着座位置に回動部33を回す際、付勢により補助されるため、小さな力で済む。尚、トーションバネ87の強さにより、前記復帰の動作と前記補助の動作のいずれかに設定できる。   Therefore, when the occupant descends and turns the lock after turning the turning portion 33 to the turning position, the turning portion 33 returns to the seating position by the bias of the torsion spring 87, or the turning portion 33 moves to the seating position. When turning 33, it is assisted by urging, so that only a small force is required. Note that, depending on the strength of the torsion spring 87, either the return operation or the auxiliary operation can be set.

このように本実施例では、回動位置から着座位置に回動部33を回動付勢する復帰手段86を備えるから、着座位置への回動部33の復帰が容易となる。   As described above, in the present embodiment, since the return means 86 for urging the turning portion 33 to turn from the turning position to the sitting position is provided, the turning portion 33 can be easily returned to the sitting position.
