Abstract: A vehicle seat of the present invention includes: a seat cushion frame that supports the buttocks and thighs of a seated occupant; a cloth-form member that is attached to the seat cushion frame, that extends along a seat front-rear direction and a seat width direction, that has stretch properties, and that supports a load of the seated occupant; and an elongated member that is fixed at a lower face side of, or inside, a seat front-rear direction intermediate portion of the cloth-form member, and that is formed in an elongated shape with its length direction along the seat width direction.

Abstract: A headrest supporting structure is provided with a lower spring and an upper spring, which are located at different positions in the vertical direction of a seat. The structure elastically supports a headrest stay with the springs. When a stopper section, which changes the position in the front-back direction in accordance with pivoting of the headrest, comes into contact with a support bracket, further pivoting of the headrest is restricted. The stiffness of the upper spring located relatively distant from the stopper section in the seat vertical direction is higher than that of the lower spring located closer to the stopper section.

Abstract: A vehicle seat equipped with a side airbag apparatus and method thereof that even if a pad side face portion and pad rear face portion of a seatback pad are disposed at a vehicle width direction outer side and vehicle rearward side of a side frame at a side opposing a vehicle body side portion, improve assembly operations. The webbing sewn into a loop shape along a cover cleaving portion, and the airbag module is inserted into the webbing. An opening portion formed between front face and side face portions of a side pad portion of the seatback pad, and the airbag module and webbing are inserted through the opening portion. The side face and rear face portions connecting to one another by a reduced thickness portion. Accordingly, the rear face portion may turn about the reduced thickness portion and a nut may fasten from the vehicle rearward side.

Abstract: An environment risk analysis system includes: a probe terminal configured to acquire environment data including an atmosphere density; an environment analysis client configured to receive threshold data for analysis of an environment risk, specify an analysis-target area in geographic information, output the threshold data and data of the specified analysis-target area, receive an analysis result of the environment risk of the specified analysis-target area, and display data based on the analysis result in layers on the geographic information; and an environment analysis server configured to analyze the environment risk of the specified analysis-target area based on the environment data, the threshold data and the data of the specified analysis-target area, to output the analysis result. The environment analysis server calculates an estimation of a degree of an environmental influence based on the environment data, and calculates an estimation of an exposure rate of the environmental influence.

Abstract: A headrest support structure includes: a support member configured to support a protruding member projecting from a headrest; a bracket provided in a seatback and having an accommodation chamber in which the support member is accommodated in a tiltable manner in a front-rear direction perpendicular to a width direction of the headrest; a spring provided in the accommodation chamber and deforming in a bending manner due to tilting of the support member relative to the bracket in the front-rear direction; and a projection portion projecting, in the front-rear direction, from one of an outer surface of the support member and an inner surface of the bracket which are opposed to each other. The projection portion is provided at a position different from the spring in a regulation direction perpendicular to both the front-rear direction and the width direction of the headrest.

Abstract: Two headrest stays-are supported such that, when the tilting amount in the seat front-rear direction of the headrest stays-relative to a seatback frame is within a specified range, the support stiffness of a headrest relative to the seat front-rear direction is reduced in comparison to when the tilt amount is outside the range. The two headrest stays are secured to be swingable in the seat front-rear direction in the headrest.

Abstract: A headrest support structure includes: a metal tubular support bracket configured to be provided in a seatback frame; a resin headrest support configured to support a headrest stay and inserted into the support bracket; and a spring disposed between the support bracket and the headrest support. The headrest support is elastically supported in a swingable manner relative to the support bracket so as to make a headrest function as a dynamic damper. The spring is a metal leaf spring provided integrally with the headrest support.

Abstract: A location-information discrimination method and device are provided that can accurately discriminate between locations of a mobile terminal in keeping with an actual environment. A discrimination value calculator calculates a discrimination value that is dependent on the amount of a change, from a predetermined value, in the received power of a radio signal received by a mobile terminal from a base station and on the duration of that change in the received power. The determination section compares the discrimination value with a predetermined value, thereby determining whether the mobile terminal is located indoors or outdoors.

Abstract: A calculation ?i=0N?1e(R(i, 0), . . . , R(i, K?1)) where a calculation of K elements R(i, k)?GF(pm) of a finite field GF(pm) over a finite field is expressed as e(R(i, 0), . . . , R(i, K?1)) is efficiently performed. Polynomials poly(R(i, 0), . . . , R(i, K?1)) that express a d-th-order extension field of the finite field GF(pm), which are obtained by the calculations e(R(i, 0), . . . , R(i, K?1)) for different values of i, are multiplied by each other, and a cumulative multiplication of the products is performed, for example. The polynomial poly(R(i, 0), . . . , R(i, K?1)) is a mapping from the input elements of the finite field GF(pm), and the coefficients of at least some of the terms thereof are 0. The same process is performed for different sets of values of i, and the calculation ?i=0N?1e(R(i, 0), . . . , R(i, K?1)) is performed using the result.
